PREPARATION OF BENZOIC ACID ANILIDE

PURPOSE:To obtain a benzoic acid anilide useful as a germicide in high yield inexpensively, by using water, etc. as a solvent, reacting a benzoic acid halide with an aniline in the presence of a dehydrohalogenating agent with strong stirring. CONSTITUTION:An o-substituted benzoic acid halide shown b...

Zusammenfassung:	PURPOSE:To obtain a benzoic acid anilide useful as a germicide in high yield inexpensively, by using water, etc. as a solvent, reacting a benzoic acid halide with an aniline in the presence of a dehydrohalogenating agent with strong stirring. CONSTITUTION:An o-substituted benzoic acid halide shown by the formula I (R1 is CH3, CF3, or I; X is halogen) is reacted with an aniline shown by the formula II(R2 is isopropoxy) in water or water-organic solvent in the presence of both a dehydrohalogenating agent and a phase transfer catalyst at 0-100 deg.C, preferably at
