Reaction Conditions

Reaction Steps

N-chlorosuccinimide (0.42 g, 3.2 mmol) was added to a solution of N-(2-{[1-(phenylsulfonyl)-1H-indol-5-yl]oxy}ethyl)acetamide (Intermediate 25, 0.95 g, 2.6 mmol) in THF (20 ml) at room temperature. The reaction mixture was stirred at 40° C. for 6 hours. The reaction mixture was evaporated and the crude material was purified by flash chromatography on silica gel using 3% MeOH in DCM as the eluent to give the title compound (1.11 g) as a white solid. MS m/z 393 [M+H]+.
