Description
Fremgangsmåte til fremstilling av N-metyl-«-fenylsuccinimid. Process for the preparation of N-methyl-«-phenylsuccinimide.
N-metyl-a-succinimid er blitt et meget verdifullt middel ved behandling av den mildere form for epilepsi (petit mal). Etter amerikansk patent nr. 2 643 258 kan denne forbindelse fremstilles av fenylravsyre eller fenylravsyreanhydrid, ved å la den reagere med metylamin og ved opp-varming av det dannede produkt. Fremgangsmåten lider av den mangel at den krever bruk av fenylravsyre eller fenylravsyreanhydrid, begge meget dyre utgangsmaterialer. Ved hjelp av fremgangsmåten ifølge oppfinnelsen kan N-metyl-a-fenylsuccinimid fremstilles av lett tilgjengelige, billige utgangsmaterialer. N-methyl-a-succinimide has become a very valuable agent in the treatment of the milder form of epilepsy (petit mal). According to US Patent No. 2,643,258, this compound can be prepared from phenylsuccinic acid or phenylsuccinic anhydride, by allowing it to react with methylamine and by heating the product formed. The process suffers from the shortcoming that it requires the use of phenylsuccinic acid or phenylsuccinic anhydride, both very expensive starting materials. By means of the method according to the invention, N-methyl-a-phenylsuccinimide can be produced from readily available, cheap starting materials.
I henhold til oppfinnelsen kan denne forbindelse og andre forbindelser som er omtalt i det følgende, fremstilles ved å la fenylmaleinsyreanhydrid reagere med metylamin ved en temperatur mellom 80 og 110° C. Derved dannes N-metyl-a-fenylmaleinsyreimid. Derpå reduserer man den alifatiske dobbeltbinding som finnes i N-metyl-a-fenylmaleinsyreimidet. According to the invention, this compound and other compounds mentioned below can be prepared by allowing phenylmaleic anhydride to react with methylamine at a temperature between 80 and 110° C. N-methyl-a-phenylmaleic imide is thereby formed. The aliphatic double bond found in the N-methyl-α-phenylmaleic acid imide is then reduced.
Ved utførelsen av reaksjonen mellom fenyl-maleinsyreanhydrid og metylamin anvendes en ekvivalent mengde, eller fortrinsvis et lite overskudd av den beregnede mengde .metylamin. Reaksjonen kan ut-føres i vann, et organisk oppløsningsmid-del eller en blanding av vann og et med vann blandbart organisk oppløsningsmid-del. Andre brukbare oppløsningsmidler enn vann er lavere alifatiske alkoholer When carrying out the reaction between phenylmaleic anhydride and methylamine, an equivalent amount, or preferably a small excess of the calculated amount of methylamine, is used. The reaction can be carried out in water, an organic solvent or a mixture of water and a water-miscible organic solvent. Other usable solvents than water are lower aliphatic alcohols
som metanol, etanol og isopropanol, cykli-ske etere så som dioksan, estere som etylacetat, vandige blandinger av de her nevn-te stoffer og lignende. Av hensyn til om- such as methanol, ethanol and isopropanol, cyclic ethers such as dioxane, esters such as ethyl acetate, aqueous mixtures of the substances mentioned here and the like. For reasons of re-
kostningene er vann å foretrekke. Den foretrukne temperatur for reaksjonens ut-førelse er 95—100° C. Reaksjonen forløper hurtig og er vanligvis ferdig etter y2—2 timer. costs are water preferred. The preferred temperature for carrying out the reaction is 95-100° C. The reaction proceeds rapidly and is usually completed after y2-2 hours.
Reduksjonen av den alifatiske dobbeltbinding i N-metyl-rt-fenylmaleinsyreami-det blir fortrinsvis utført ved hjelp av hydrogengass og en metallisk hydrerings-katalysator. Som hydreringskatalysatorer gir Raney-nikkel og edelmetallkatalysa-torer som platinaoksyd særlig godt resul-tat. Reduksjonen kan utføres ved en temperatur mellom 15—100° C. Hydrogen-trykket er ikke særlig avgjørende og kan varieres fra en til et hundre atmosfærer eller mere. Gode resultater er oppnådd med et hydrogengasstrykk på ca. 2,5—6 atm., og følgelig er det ikke nødvendig med høyere trykk. Som oppløsningsmiddel kan brukes estere, som etylacetat, lavere alifatiske alkoholer, som metanol, etanol, isopropanol, og blandinger av estere og lavere alifatiske alkoholer. The reduction of the aliphatic double bond in the N-methyl-rt-phenylmaleic acid amide is preferably carried out with the aid of hydrogen gas and a metallic hydrogenation catalyst. As hydrogenation catalysts, Raney nickel and noble metal catalysts such as platinum oxide give particularly good results. The reduction can be carried out at a temperature between 15-100° C. The hydrogen pressure is not particularly decisive and can be varied from one to one hundred atmospheres or more. Good results have been achieved with a hydrogen gas pressure of approx. 2.5-6 atm., and consequently a higher pressure is not necessary. As a solvent, esters, such as ethyl acetate, lower aliphatic alcohols, such as methanol, ethanol, isopropanol, and mixtures of esters and lower aliphatic alcohols can be used.
I det følgende beskrives som eksempel en utførelsesform for oppfinnelsen. In the following, an embodiment of the invention is described as an example.
Eksempel: Example:
En blanding som består av 4 g fenyl-maleinsyreanhydrid og 3,5 ml av en 23 pst. oppløsning av metylamin i vann oppvar-mes på dampbad i en time. 10 ml koldt vann tilsettes, blandingen kjøles, og det utfelte N-metyl-a-fenylmaleinsyreimid fil-treres fra. Utbytte 2 g, smeltepunkt 145— 147° C. A mixture consisting of 4 g of phenyl-maleic anhydride and 3.5 ml of a 23% solution of methylamine in water is heated on a steam bath for one hour. 10 ml of cold water are added, the mixture is cooled, and the precipitated N-methyl-α-phenylmaleic acid imide is filtered off. Yield 2 g, melting point 145-147° C.
100 mg platinaoksyd som hydrerings- 100 mg platinum oxide as hydration
katalysator tilsettes til en oppløsning av 4 g N-metyl-a-feny!lmaleinsyreimld i en blanding av 100 ml absolutt etanol og 100 ml etylacetat. Blandingen rystes i et luk-ket kar med vannstoffgass ved et trykk på 3,45 kg/cm2 inntil den teoretiske mengde hydrogen er absorbert. Trykket avblåses, og karet åpnes, katalysatoren frafiltreres, og filtratet indampes til et volum på ca. 15 ml. Oppløsningen filtre-res, filtratet avkjøles, og det utfelte N-metyl-a-fenylsuccinimid frafiltreres. Utbytte 3 g, smeltepunkt 70—72° C. catalyst is added to a solution of 4 g of N-methyl-α-phenylmaleic acid imld in a mixture of 100 ml of absolute ethanol and 100 ml of ethyl acetate. The mixture is shaken in a closed vessel with hydrogen gas at a pressure of 3.45 kg/cm2 until the theoretical amount of hydrogen has been absorbed. The pressure is released, and the vessel is opened, the catalyst is filtered off, and the filtrate is evaporated to a volume of approx. 15 ml. The solution is filtered, the filtrate is cooled, and the precipitated N-methyl-α-phenylsuccinimide is filtered off. Yield 3 g, melting point 70-72° C.
Om ønskes kan de 100 mg platinaok-sydkatalysator som er brukt i ovennevnte forsøk erstattes med ca. 0,5 g Raney-nik-kelkatalysator. If desired, the 100 mg of platinum oxide catalyst used in the above experiment can be replaced with approx. 0.5 g of Raney nickel-nickel catalyst.
Fenylmaleinsyreanhydrid som brukes som et av utgangsstoffene ved utførelsen av oppfinnelsen, kan fremstilles billig og lett ved å la maleinsyreanhydrid reagere med benzen og klor under innvirkning av ultraviolett lys. Phenylmaleic anhydride, which is used as one of the starting materials in carrying out the invention, can be produced cheaply and easily by allowing maleic anhydride to react with benzene and chlorine under the influence of ultraviolet light.
