Participants

Reaction Steps

To sodium hydride (0.174 g, 4.35 mmol) in tetrahydrofuran (6.8 mL, 0.084 mol), 1H-Indole-6-carbaldehyde (59, 0.486 g, 3.35 mol) was added. After 30 minutes, propane-1-sulfonyl chloride (0.565 mL, 5.02 mol) was added. After two hours, it was quenched with 1M HCl (aqueous) and extracted twice with ethyl acetate. The combined organic layers were washed with brine, dried over anhydrous sodium sulfate and filtered. The filtrate was concentrated. The desired compound was purified by silica gel column chromatography eluting with a gradient of ethyl acetate in hexane to give 516 mg of desired compound. MS (ESI) [M−H+]−=250.1.
