4-acetylamino-5-chloro-2-methoxy benzoyl chloride (2.70 g, 0.0103 mole) in anhydrous benzene (100 ml) in the presence of triethylamine (1.1 g) was treated with 4-methyl-1-amino piperazine (1.18 g). After 6 hours the reaction mixture was basified with dilute sodium hydroxide and extracted with hot ethyl acetate. On cooling the extracts yielded 4-acetylamino-5-chloro-2-methoxy-N-[4-methyl-1-piperazinyl]benzamide (1.72 g), m.p. 198°-200° C.
