Procedure

A solution of 1-hydroxybenzotriazole monohydrate (112 mg, 0.73 mmol) and 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (153 mg, 0.80 mmol) in N,N-dimethylformamide (5 ml) was added to (E)-3-(2-quinolinyl)-2-propenoic acid (M. Hamana, K. Funakoshi and Y. Kuchino, Chem. Pharm. Bull., 1974, 22, 1806; 131 mg, 0.66 mmol). After stirring at room temperature for 15 min, the mixture was added to the hydrochloride salt of N-[3-(6-methyl-3-azabicyclo[3.1.0]hex-6-yl)phenyl]methanesulfonamide (Preparation 53, 202 mg, 0.66 mmol) and sodium hydrogen carbonate (110 mg, 1.32 mmol). The reaction mixture was stirred at room temperature for overnight and then water (10 ml) and dichloromethane (5 ml) were added. The biphasic mixture was separated by filtering through a Whatman Microfiltration Device Filter Tube, and the resulting organic extract was concentrated using a stream of nitrogen to afford 400 mg of a crude dark red oil. This was purified by chromatography using a Biotage Flash 40S™ cartridge packed with silica gel (40 g) eluting with dichloromethane:ethanol: 0.880 ammonia (100:2 1) to afford the title compound as a cream solid (206 mg, 70%).
