実験手順
Method I Combine 6-amino-1-isopropyl-3-(3,4,5-trifluoro-phenyl)-1H-indole (116.6 mg, 0.38 mmol), prepared as described immediately above, dichloromethane (3.0 mL) and pyridine (62 μL, 0.76 mmol) under a nitrogen atmosphere in a 25 mL flask. Cool the reaction to 0° C. and add methane sulfonyl chloride (33 μL, 0.42 mmol). Allow the reaction to warm to RT while stirring for 3 hours. Quench reaction with saturated aqueous sodium bicarbonate (5 mL), dilute with ethyl acetate (10 mL) and separate the layers. Wash the organic layer with water (5 mL), brine (5 mL), dry (Na2SO4) and filter. Concentrate the filtrate and adsorb the crude product onto silica gel. Purify by silica gel chromatography eluting with ethyl acetate in dichloromethane (0-5 v/v %) to give 95.1 mg of the title compound (61%). LRMS (API ES+)=383.0 (M+H).
