Reaction Steps

N-(3-methyl-butyl)-N'-nitroso-piperazine (2.5 g.) was added to 4-acetylamino-5-chloro-2-methoxy-benzoyl chloride (prepared from 3.5 g. of corresponding acid and thionylchloride) and triethylamine (5 ml.) in anhydrous toluene (250 ml.). After 1 hour, 10% sodium hydroxide (5 ml.) was added and the toluene layer separated, dried and evaporated to give 4-acetylamino-5-chloro-2-methoxy-N-[4-(3-methylbutyl)-1-piperazinyl]benzamide (3 g., 52%), m.p. 128°-30° (ex-ethylacetate/light petroleum.
