Abstract

PURPOSE:To obtain the titled compound in high yield, in some cases via an intermediate, by chlorinating O-sulfonyl-N-pyrazolylamidoxime, N- pyrazolylamidine or N-pyrazolylimidic acid ester. CONSTITUTION:The objective compound of formula VI useful as an intermediate for the synthesis of a magenta coupler for silver halide color photographic material in high yield and efficiency can be produced by chlorinating a compound of formula I-III (R1 is H, alkyl, aryl, alkoxy or aryloxy; R2 is H, alkyl, aryl or heterocyclic group; R3 and R4 are alkyl or aryl; X is acid radical; n is 0 or positive number). The objective compound is obtained directly from the compound of formula I, via the compound of formula IV from the compound of formula II or via the compound of formula V from the compound of formula III.
