To a solution of the hydrochloride salt of N-[3-(6-methyl-3-azabicyclo[3.1.0]hex-6-yl)phenyl]methanesulfonamide (Preparation 53, 50 mg, 0.165 mmol) in N,N-dimethylformamide (2 ml) was added sodium hydrogen carbonate (35 mg, 0.413 mmol) and 3-(2-bromoethyl)indole (37 mg, 0.165 mmol). The reaction mixture was heated at 55° C. for 48 h, cooled to room temperature and concentrated in vacuo. Water (10 ml) was added and the product was extracted with ethyl acetate (3×10 ml). The combined organic extracts were dried (Na2SO4), filtered and concentrated in vacuo to give a brown oil. The crude product was purified by chromatography using a Biotage Flash 12™ cartridge packed with silica gel (8 g), eluting with hexane:ethyl acetate (100:0 and then 0:100). The title compound was obtained as a glass (22 mg, 33%).
