3 M NaOH (5 mL, 15 mmol) was added to a solution of 5-(benzyloxy)-6-methoxy-indole (1.0 g, 3.9 mmol), tetrabutylammonium hydrogen sulfate (0.400 g, 1.18 mmol) and benzenesulfonyl chloride (1.04 g, 5.92 mmol) in DCM (25 mL). The mixture was stirred overnight at room temperature and diluted with DCM and water. The organic phase was washed with water (1×), dried (MgSO4) and evaporated. The crude product was purified through a plug of silica gel using DCM as the eluent to give the title compound (1.1 g) as a white solid. MS m/z 394 [M+H]+.
