Participants

Reaction Steps

1-(Phenylsulfonyl)-4-vinyl-1H-indole (190 mg, 0.7 mmol, Intermediate 45) was weight in to a pre dried reaction flask and purged with nitrogen gas for 1 h. Dry THF (50 mL) was added and the reaction flask was cooled to −78° C. before LDA (0.35 mL, 0.7 mmol, 2M) was added. The reaction was stirred for 15 minutes before iodomethane (95.2 mg, 0.7 mmol) was added. Allowed the reaction mixture to slowly reach RT ON. Added 1 mL MeOH and evaporated the reaction mixture on silica. Purified by flash chromatography using 20% DCM in hexanes. Got 61 mg of a white solid, 30% yield. MS (ESI+) for C17H15NO2S m/z 298 (M+H)+.
