Reaction Steps
To a solution (10 mL) of 5-phenyl-1H-pyrrole-3-carbaldehyde (100 mg) in tetrahydrofuran was added sodium hydride (60% in oil, 47 mg) at room temperature and the mixture was stirred for 30 min. 15-Crown-5 (257 mg) was added dropwise and the mixture was stirred for 30 min, 2-benzothiophenesulfonyl chloride (204 mg) was added, and the mixture was further stirred for 1 hr. Saturated brine was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The extract was washed with saturated brine, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (eluent: hexane-ethyl acetate=4:1→3:2) to give the title compound as a colorless oil (yield 180 mg, 84%).
