실험 절차

A solution of 8-chloro-10-phenyl-1,2,3,4-tetrahydropyrazino-[1,2-a]indole-1-one (6.0 g, 0.0202 mole) in dimethyl formamide (40 ml) is added over a period of 1/2 hour to a suspension of sodium hydride (1.4 g, 0.029 mole of a 50% dispersion in mineral oil) in dimethylformamide (20 ml). The mixture is stirred at about 35° C. for 1 hour. A solution of freshly distilled N-(β-chloroethyl)pyrrolidine (3.88 g, 0.029 mole) in dimethylformamide (10 ml) is added over a period of 1/4 hour. The reaction mixture is stirred at 50° C. for 18 hours, then cooled and poured into water (300 ml), this mixture is extracted with dichloromethane (4 portions, 100 ml each). The extracts are washed with saturated sodium chloride solution and dried over anhydrous sodium sulfate. The drying agent is removed by filtration and the filtrate is concentrated. The residue is recrystallized from heptane to give the above titled product, 6.15 g (77.3 % yield), melting at 134°-135.5° C.
