Sodium hydride → HCID 86620756, compound

Participants

Reaction Steps

Under an argon atmosphere, 5-phenyl-1H-pyrrole-3-carbaldehyde (514 mg) was dissolved in absolute tetrahydrofuran (15 mL), and sodium hydride (60% in oil, 180 mg) was added at room temperature while stirring. After stirring at the same temperature for 15 min, 15-crown-5 (0.90 mL) was added, and the mixture was further stirred at the same temperature for 15 min. 6-Chloropyridin-3-ylsulfonyl chloride (827 mg) was added, and the mixture was further stirred at the same temperature for 1 hr. The reaction mixture was diluted with ethyl acetate, washed successively with saturated aqueous sodium hydrogencarbonate solution and saturated brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure and the residue was purified by silica gel column chromatography (eluent: hexane-ethyl acetate=19:1→7:3) to give the title compound as an oil (yield 762 mg, 73%).
