실험 절차

To a solution of 8.5 g (0.03 mole) of the base of 4-[4-(phenylmethyl)-1-piperazinyl)benzeneamine and 16.0 g (0.16 mole) of triethylamine in 450 ml of ethyl acetate was added, dropwise, a solution of 2.5 g (0.035 mole) of acetyl chloride in 50 ml of ethyl acetate. The mixture was magnetically stirred for 3 hr and then heated at reflux for 1 hr. The excess acetyl chloride was co-distilled with benzene and the resulting oil was shaken in 400 ml of 10% sodium hydroxide solution. The suspended tan solid was collected by filtration, washed thrice with 100 ml portions of water, and air dried to give 9.7 g (99%) of crude product. A one gram portion was recrystallized from benzene/petroleum ether to give 100 ml of cream colored solid, m.p. 159°-161° C.
