Procedure
3-Chlorophenyl isocyanate (36 mg, 0.23 mmol) was added to a solution of (S)-3-methyl-1-(3-piperidin-1-yl-propyl)-piperazin-2-one (intermediate 20; 52 mg, 0.21 mmol) and 4-methylmorpholine (21 mg, 0.21 mmol) in N,N-dimethylformamide (1 ml), then after 16 h the reaction mixture was partitioned between ethyl acetate and water. The organic layer was washed with brine, dried (MgSO4), filtered, and evaporated. Chromatography (SiO2; dichloro-methane/methanol/25% aq. ammonia solution 90:10:0.25) produced the title compound (68 mg, 84%). Colorless gum, MS (ISP)=393.2 (M+H)+.
