Abstract

PURPOSE: To obtain in high yields the titled compound useful as an intermediate for a color producing agent of pressure-sensitive copying paper, by condensing a benzaldehyde derivative with a benzoic acid derivative to give a condensate, followed by oxidizing the condensate without isolation.
CONSTITUTION: A benzaldehyde derivative shown by the formula I (X is H, halogen, nitro, alkyl, substituted alkyl, amino, or OH ; m is 1W4) is condensed with a benzoic acid derivative shown by the formula II (Y is amino or substituted amino ; R is H or alkyl) in the presence of a condensation agent to give a condensate, which is not isolated, and oxidized with an oxidizing agent in the presence of an alkali or after being dissolved in an alkali aqueous solution, to give a benzophenone derivative shown by the formula III. The first condensation process provides mainly a black resinious substance, which is oxidized without isolation to give the desired substance in high yields.
