Participants

Reaction Steps

Under ice-cooling, to dimethylformamide (0.2 ml) was added dropwise sulfuryl chloride (0.17 ml), and the mixture was stirred, under nitrogen atmosphere, at room temperature for 10 minutes. To the mixture was added 7-(4-methylphenyl)-2,3-dihydro-1-benzoxepine (0.3 g), and the mixture was stirred, under nitrogen atmosphere, at 90° C. for 3 hours. To the mixture was added ice-water, and the mixture was extracted with ethyl acetate. The organic layer was washed with water and saturated brine, and dried with anhydrous magnesium sulfate. The solvent was evaporated to give 7-(4-methylphenyl)-2,3-dihydro-1-benzoxepine-4-sulfonylchloride (0.36 g) as pale yellow crystals.
