Definitions
- the present invention relates to a method for producing 2′-doxy_2′-fluoroperidine, which is an important intermediate of pharmaceuticals.
- 2′-Doxy_2,1-fluorouridine which is the subject of the present invention, is an important intermediate of pharmaceuticals.
- the conventional manufacturing method can be broadly divided into the following two.
- Non-Patent Document 1 J. Org. Chem. (USA), 1964, 2nd edition). 9, Vol. 3, No. 3, p. 558-564.
- Non-Patent Document 3 (Tetrahedron Lett., UK), 197, Vol. 18, No. 15, p. 9 1 — 1 294), Non-Patent Document 4 (Chem. Pharm. Bull. (Japan), 1981, Vol. 29, No. 4, p. 1034 — 1038), Non-Patent Document 5 (J. Carboh- y- d.Nuc1.Nuc1. (UK), 1980, Vol. 7, No. 2, p. 1 Non-Patent Document 6 (Chem. Pharm. Bui 1. (Japan), 1981, Vol. 29, No. 11, p. 32881 -See 3 285)).
- Non-Patent Document 1 In the method for producing 2,2-doxy-1,2-fluoroperidine disclosed in Non-Patent Document 1, the reaction is carried out using excessively hydrofluoric acid, which is highly corrosive, at a high temperature, and therefore the material of the reactor is significantly reduced. There were serious restrictions. In addition, the productivity was poor because the substrate was highly diluted with the reaction solvent, and the reaction yield itself was low. Further, from an industrial point of view, a large amount of hydrofluoric acid, which is difficult to handle, is used, and purification of the obtained product requires column chromatography. Was hard to say.
- Non-Patent Document 2 it is necessary to use a special fluorinating agent that is industrially expensive and has a problem in handling a large amount, and the reaction yield is moderate. The method was hard to say.
- Non-Patent Documents 3 to 6 gives the target compound only in a very low yield. Did not.
- Non-Patent Documents 3 to 6 in which a 2′-triflate is fluorinated to obtain 2′-deoxy-2,1-fluoroadenosine or 2′-deoxy-2,1-fluoroguanosine is as follows: fluorine Anion (F-), but due believed nucleophilic S N 2 displacement reaction, in its apply in this reaction as a side reaction "elimination reaction of tri freight group (CF 3 S 0 3 one group)" Occurs in competition with each other, and a by-product in which the 1-position carbon and the 2'-position carbon are connected by a double bond is by-produced.
- F- fluorine Anion
- An object of the present invention is to provide an industrial process for producing 2′-dexoxy-2′-fluoroperidine, which is an important intermediate of pharmaceuticals.
- Another object of the present invention is to provide an industrial production method of 2, 3 ', 5' monohydroxyl-protected form of 2'-deoxy-1'-fluorinidine which is a precursor of 2'-doxy-1'-fluorinidine.
- the present invention relates to the formula [1]
- R represents a protecting group for a hydroxyl group
- R represents a protective group for a hydroxyl group
- T f represents CF 3 S 0 2 group
- 2 ' represented by - converting the preparative Rifureto body, then consisting of "organic bases and hydrofluoric acid, By reacting with a fluorinating agent consisting of “salt or complex”
- the present invention provides a first method for producing a protected 3 ′, 5, monohydroxyl group of 2′-doxy-12′-fluoroperidine, represented by the formula: wherein R represents a hydroxyl-protecting group.
- the first method described above may be a second method.
- the second method is the equation [2]
- the method is the same as the first method, except that the above-mentioned trifluoromethanesulfonylating agent represented by is a trifluoromethanesulfonylating agent represented by the formula [5].
- the first method may be a third method.
- the equation [6] the equation [6]
- THP represents a tetrahydrovinylalanyl group
- 1 D-arabinofuranosylperacyl 3 ′, 5′—Protected hydroxyl group is converted to a compound of the formula [ Five ]
- THP represents a tetrahydrovinylyl group and Tf represents a CF 3 S ⁇ 2 group
- Tf represents a CF 3 S ⁇ 2 group
- THP represents a tetrahydrovinylyl group
- a protected 3,5 ′ monohydroxy group of 2, -deoxy_2,1-fluorouridine is produced.
- the present invention provides a method according to any one of the above first to third methods, wherein the formula [4]
- R represents a hydroxyl-protecting group
- the present invention provides a fourth method for producing 2'-dexoxy 2'-fluorouridine represented by the formula:
- the fifth method may be the sixth method.
- the sixth method is the same as the fifth method, except that 2, -dexoxy-2,1-fluoroperidine represented by the formula [9] is produced by the fourth method.
- the present inventors have conducted intensive studies in order to solve the above-described problems, and as a result, the 3 ′, 5 ′ monohydric protected form of 1 — / 3— D-arabinofuranosylperacyl, which is the object of the present invention, the when the substrate, 'triflic O b methanesulfonylation in position, and subsequent 2' 2 aimed position nucleophilic S N 2 substitution reaction with fluorine Anion (F-) in the specific conditions We made it clear that we were going well.

- the recovered organic layer was concentrated under reduced pressure to obtain 79.4.54 g of a crude product of a protected 3 ′, 5, monohydroxy group of 2′-deoxy 2′-fluorinidine represented by the above formula .
- the recovered amount of the crude product exceeded the theoretical yield of 28.69 g.
- the 19 F-NMR spectrum of the 3 ′, 5, monohydric protected form of 2′-deoxy-1 2′-fluoridine was similar to that shown in [Example 1].
- the total yield from 2,2,1-anhydrolidine to 3,4-, 5-diacetyl-purified 2,4-hydroxyl 2'-fluoride was a total of 62% (the weight of the theoretical yield was 230%). .86 g) o
- the high purity product was analyzed by liquid chromatography to find that the HPLC purity was 99.8%.
- the first step the trifluoromethanesulfonylation step, Second step fluorination step
- the 19 F-NMR spectrum of the 3,5′-hydroxyl-protected form of 2′-doxy-2,1-fluoridine was similar to that shown in [Example 1].
