4-Toluenesulfonyl chloride → HCID 86664379, compound

Participants

Reaction Steps

To a suspension of sodium hydride (240 mg, 5.9 mmol) in THF (10 mL) was added 1H-indole-7-carbaldehyde (570 mg, 3.9 mmol) at room temperature. After being stirred at room temperature for 20 min, 4-methylbenzene-1-sulfonyl chloride (1.1 g, 5.9 mmol) was added to the mixture. The mixture was stirred at room temperature for 1 hour. The mixture was poured into saturated ammonium chloride aqueous solution, and the aqueous phase was extracted with ethyl acetate (twice). The combined organic layers were dried over magnesium sulfate and concentrated in vacuo. The residue was purified by column chromatography on silica gel eluting with hexane/ethyl acetate (4:1 (v/v)) to give 1.0 g (89% yield) of the title compound as a white solid:
