反应详情

A solution of 2-(4-(4-(aminomethyl)phenylmethyl)piperazin-1-yl)pyrimidine (0.5 g), propionic chloride (0.18 ml) and triethylamine (0.3 ml) in methylene chloride (20 ml) was stirred at room temperature for 2 hr. The reaction mixture was washed with water and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure to give a pale-yellow substance (0.8 g). The obtained pale-yellow substance was crystallized from hexane/ethyl acetate (1:1, 50 ml) to give the title compound (0.5 g) as pale-yellow crystals.
