Versuchsvorschrift

To a solution of the hydrochloride salt of N-[3-(6-methyl-3-azabicyclo[3.1.0]hex-6-yl)phenyl]methanesulfonamide (Preparation 53, 200 mg, 0.66 mmol) in N,N-dimethylformamide (8 ml) was added sodium hydrogen carbonate (3 g, 36 mmol) and (S)-3-cyclohexyl-3-hydroxypropyl 4-bromobenzenesulfonate (J. A. Werner et al, J. Org. Chem., 1996, 61, 587) (0.08 ml, 0.89 mmol) and the reaction mixture was heated at 50° C. for 20 h. After cooling, diethyl ether (15 ml) and water (15 ml) were added and the reaction mixture was stirred vigorously for 5 min. The phases were separated and the aqueous layer was further extracted with diethyl ether (2×15 ml). The combined organic extracts were dried (Na2SO4), filtered and concentrated in vacuo. The residual oil was purified by flash column chromatography using a Sep-Pak™ cartridge packed with silica gel (10 g) eluting with dichloromethane:ethanol:0.88 ammonia solution (200:8:1) to afford the title compound as an oil (90 mg, 25%).
