Reaction Steps

A mixture consisting of 44.7 g. (0.20 mole) p-bromophenylhydrazine hydrochloride, 250 ml. diethyl ether, 70 ml. (0.504 mole) triethylamine, and 35.0 g. (0.20 mole) p-chlorobenzoyl chloride in 50 ml. diethyl ether (mixed in that order at -5° to -15° C. during 20 minutes) was stirred continuously for about 16 hrs. at about 25° C. The reaction mixture was filtered, and the solids on the filter were washed with water and then recrystallized from 95% ethanol. There was thus obtained 15.5 g. p-chlorobenzoic acid (p-bromophenyl)hydrazide having a melting point of 185° C. (dec.). An analytical sample melting at 184.5° C. (dec.) was obtained after two recrystallizations from ethyl acetate.
