Procedure

A solution of 4-(3-fluorophenoxy)benzoic acid (0.180 g, 0.775 mmol), 2-(5-chloro-1H-indol-3-yl)ethanamine hydrochloride (0.180 g; 0.775 mmol), HATU (0.324 g; 0.852 mmol) and N,N-diisopropylethylamine (0.334 mL; 1.94 mmol) in DMF (5 mL), was stirred at room temperature overnight. The reaction mixture was partitioned between ethyl acetate and sodium hydrogen sulfate, the organic layer was washed with sodium carbonate, brine, dried and concentrated under reduced pressure. The crude mixture was purified by flash chromatography on silica (eluent 2 to 20% ethyl acetate in dichloromethane and 20 to 100% ethyl acetate in heptane) to yield 0.065 g (20%) of the title compound as a white solid.
