Participants

Reaction Steps

To a solution of (E)-3-(4-{1-[2-(6-amino-2-tert-butyl-1H-indol-3-yl)-ethyl]-pyrrolidin-2-yl}-phenyl)-acrylic acid methyl ester (0.70 g, 1.6 mmol) in dichloromethane (7 mL) was added methanesulfonyl chloride (0.198 g, 1.73 mmol), triethylamine (241 μL, 1.73 mmol). The resulting solution was stirred at room temperature for 1 h, diluted with ethyl acetate, and washed with 1 N hydrochloric acid, a saturated sodium bicarbonate solution, and a saturated aqueous solution of sodium chloride. The organic layer was dried over sodium sulfate, filtered and concentrated in vacuo. The residue was purified via silica gel column chromatography to give the title compound (0.21 g, 26% yield). LCMS (m/z): 523.9 (M+1).
