Procedure

To a solution of 3-(4-fluorophenyl)propanoic acid (104 mg, 0.62 mmol) in N,N-dimethylformamide (13 ml) was added 1-hydroxybenzotriazole monohydrate (100 mg, 0.66 mmol) and 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride hydrochloride (170 mg, 0.88 mmol). After stirring at room temperature for 5 min the mixture was treated with 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) and triethylamine (133 mg, 1.32 mmol). The reaction mixture was stirred at room temperature for 72 h before concentrating in vacuo. Water (10 ml) was added and the reaction mixture was extracted with ethyl acetate (2×15 ml). The combined organic extracts were washed with water (10 ml) and saturated brine (10 ml), dried (Na2SO4), filtered and concentrated in vacuo to give a light brown oil. The residue was purified by chromatography using a Sep-Pak™ cartridge packed with silica gel (10 g) eluting with dichloromethane:ethanol:0.88 ammonia (300:8:1) to afford the title compound as a white foam (100 mg, 36%).
