Reaction Steps

A solution of N-[2-(3,4-dichlorophenyl)-2-pyrrolidin-1-yl-ethyl]benzamide (260 mg) in dimethylsulfoxide (1.5 mL) and methyl iodide (230 mg) were added to a solution of KOH (190 mg) in dimethylsulfoxide (0.7 mL). The reaction was stirred at 23° C. for 3/4 hour, was poured into water (10 mL), and extracted with dichloromethane (20 mL). The organic layer was washed (brine), dried and evaporated to a gold oil. Chromatography, with ethyl acetate:hexane (50:50 then 75:25) as the eluent, gave an oil, which was dissolved in diethylether and treated with hydrochloric acid (g)/diethylether to provide the title compound as a white solid (60 mg); mp 199-202° C.; MS: m/z=377(M+1); NMR: 1.98 (m,1), 2.12 (m,2), 2.35 (m,1), 2.54 (s,3,), 2.61 (m,1), 3.35 (m,2), 3.88 (t,1), 4.13 (m,1), 4.63 (m,2), 7.2 (dd,1), 7.26 (s,1), 7.53 (d,1), 7.79 (broad s,1), 8.11 (broad s,1), 13.23 (broad s,1). Analysis Calculated: C, 57.43; H, 5.6; N, 6.7; Found: C, 57.59; H, 5.61; N, 6.35.
