Abstract
The invention comprises compounds of the formula : <FORM:0850662/IV(b)/1> (wherein R and R1 are the same or different and are bromine or chloride atoms, alkyl groups containing 1 to 3 carbon atoms or alkoxy groups containing 1 to 5 carbon atoms or R can be an alkylmercapto group containing 1 to 5 carbon atoms, R1 being in the 3- or 5-position, and Y is a 2 to 7 carbon straight chain alkyl group or an omega-hydroxy or omega-acyloxy derivative thereof) and acid-addition salts thereof; and their preparation by the following methods (1) reacting the appropriate N-(disubstituted-phenyl)-N'-unsubstituted piperazine with a halide, sulphate or sulphonate of the group Y, conveniently in an anhydrous organic solvent ; (2) reducing a compound of the formula : <FORM:0850662/IV(b)/2> (wherein Z is - CH2 - or < CO and R1 is an alkyl group of at most 4 carbon atoms) catalytically with gaseous hydrogen and a metal catalyst such as copper chromite or by chemical means using sodium and an alcohol or a complex oxidisable metal hydride such as LiAlH4 ; (3) for compounds wherein Y is a -(CH2)3OH group, by reacting the appropriate N-(disubstituted phenyl)-N1-unsubstituted piperazine with allyl alcohol, preferably at 75 DEG to 100 DEG C.; (4) for compounds wherein Y is -(CH2)2OH, by reacting the appropriate N-(disubstituted phenyl)-N1-unsubstituted piperazine with ethylene oxide at 10 DEG to 80 DEG C.; (5) for compounds wherein Y is an omega-acyloxy radical, by acylation of the corresponding omega-hydroxy-alkyl compounds; and (6) for compounds wherein Y is an omega-hydroxy-alkyl radical, by hydrolysis or alcoholysis of the corresponding acyloxy compounds. Examples describe the preparation of compounds of the above general formula wherein R, R1 and Y have the following values : <FORM:0850662/IV(b)/3> Hydrochlorides and hydrobromides of some of the products are prepared and a further list of salt-forming inorganic and organic acids is provided. 4 - (2 : 3 - Dichlorophenyl - 1 - delta - carbometh - oxyvaleryl-piperazine is prepared by refluxing thionyl chloride with monomethyl adipate to give 5-carbomethoxyvaleryl chloride and condensing this with 1-(2 : 3-dichlorophenyl)-piperazine. Ethyl 4-(5-bromo-2-methoxyphenyl)-1-piperazine butyrate is prepared from 1-(5-bromo-2-methoxyphenyl)-piperazine and ethyl gamma-bromo-butyrate. Specification 850,663 is referred to.
