Reaction Steps

A solution of 4-chloro-7-trifluoromethylquinoline (400 mg, 0.0018 M), 1-methyl-4-[(4-aminophenyl)methyl]piperazine (400 mg, 0.0019 M) and 1.4 ml of ethanolic hydrogen chloride in 10 ml of ethanol is heated to reflux, under nitrogen for 15 minutes. The reaction mixture is quenched with ice, neutralized with aqueous 10% sodium hydroxide and extracted with methylene chloride. The methylene chloride solution is washed with water, saturated sodium chloride solution, dried over anhydrous sodium sulfate and concentrated to a white solid. This solid, after recrystallization from ethyl acetate, gives 250 mg (32%) of white crystalline 4-[[4-[(4-methyl-1-piperazinyl)methyl]phenyl]amino]-7-(trifluoromethyl)quioline of melting point 218°-220° C.
