Participants

Reaction Steps

A solution of 5-nitroindole (1.62 g, 10 mmol) in 30 ml of dimethylformamide (DMF) was treated with 60% sodium hydride (0.44 g, 11 mmol) at room temperature. After 3 minutes, benzenesulfonyl chloride (1.766 g, 10 mmol) was added. The mixture was stirred at room temperature overnight and treated with 250 ml of water. A precipitate formed and was filtered to give a yellow solid which was pumped in vacuo to give 2.7 g (89%) of the title compound.
