Procedure

To a mixture of (5-bromo-1H-indol-2-yl)-morpholin-4-yl-methanone (6.64 g, 20 mmol) in tetrahydrofuran (60 mL) was added sodium hydride (60% dispersion in oil, 979 mg, 24 mmol) in several portions. The mixture was stirred 15 min at room temperature then 2,2,2-trifluoroethyl trifluoromethanesulfonate (6.16 g, 27 mmol) was added and the reaction mixture was refluxed overnight. The reaction mixture was partitioned between ethyl acetate and an aqueous solution of sodium bicarbonate. The organic layer was washed with hydrochloric acid (1N) and brine, dried over sodium sulfate, filtered and evaporated in vacuo. The crude product was purified by flash chromatography on silica gel with dichloromethane:ethyl acetate (98:2 to 94:6 v/v) as eluant, to give 4.65 g (58%) of the desired compound as an off-white solid.
