Abstract

PURPOSE: To prepare the titled compound useful as an intermediate of pharmaceuticals, in high yield and purity, remarkably suppressing the side reactions, by reacting an aldehyde with a hydrazine in an aqueous medium maintaining the pH of the reaction system within a specific range.
CONSTITUTION: The hydrazone derivative of formula I is prepared by reacting an aldehyde of formula X-CH2CHO (X is halogen) with a hydrazine of formula H2N- NH-COR (R is lower alkoxy) in an aqueous medium at -10W+50°C maintaining the pH of the reaction system within the range 3.5W5.
