실험 절차

Triethylamine (0.23 mL, 1.67 mmol) was added to a stirred solution of 3-(4′-fluoro-biphenyl-4-yloxymethyl)-pyrrolidine-3-carboxylic acid ethyl ester (see Preparation 65) (185 mg, 0.54 mmol) in dichloromethane (10 mL) and the resulting mixture cooled to 0° C. 2-Chloro phenyl isocyanate (0.065 mL, 0.54 mmol) was added and the reaction mixture stirred at room temperature for 16 hours. The mixture was partitioned between water (25 mL) and dichloromethane (25 mL). The organic layer was separated, washed brine (25 mL), dried over magnesium sulphate and concentrated under reduced pressure. The residue was purified by column chromatography on silica gel, eluting with 25% ethyl acetate in hexane to afford the title compound as a colourless liquid (245 mg, 91%).
