Abstract

PURPOSE:To obtain a 5-acyloxypyrazole useful as an intermediate for magenta couplers in high yield, by reacting a 5-hydroxypyrazole having an amino group in the molecule with an acylating agent, etc. in the presence of a tertiary amine compound. CONSTITUTION:A 5-hydroxypyrazole of formulaI(R1 is amino, benzamido, anilino, ureido, pyrrolidino, etc.; R2 is alkyl or aryl; R3 is H, alkoxyl, aryloxy, heterocyclic oxy, etc.) is reacted with an acylating agent of formula III (R7 is halogen; R8 is alkyl, aryl, heterocyclic group, etc.) or a sulfonylating agent of formula IV (R9 and R10 are the same as R7 and R8) in the presence of a tertiary amine of formula II (R4 and R5 are 1-3C alkyl; R6 is R4, R5, aryl, etc., provided that R4, R5 and R6 may link to form a ring) at 0-50 deg.C to give a 5-acyloxypyrazole or 5-sulfonyloxypyrazole, e.g. the compound of formula V.

A method for selectively introducing and substituting various acyl groups into the amino groups of -hydroxypyrazoles is described. However, in the above method, if the acylating agent is different or the reaction is performed with a sulfonylating agent, the yield not only decreases significantly, but also it is difficult to separate by-products, and the treatment is complicated. It is not a satisfactory method as it has the disadvantage that it is too much.
No. 773f also discloses that j-hydroxypyrazoles can undergo complex reactions with acylating agents and sulfonylating agents.
