Participants

Reaction Steps

[4-(Tetrahydro-pyran-4-sulfonyl)-phenyl]-acetic acid methyl ester (1.60 gm, 5.36 mmol), NBS (1.04 g, 5.90 mmol) and benzoyl peroxide (0.130 g, 0.53 mmol) in carbon tetrachloride (50 ml) was refluxed for 7 hrs. Reaction mixture was diluted with DCM (50 ml), washed with water and brine (100 ml each), dried over anhydrous sodium sulfate, fliltered and concentrated. Crude compound was purified by column chromatography over silica gel using 30% ethyl acetate hexane as eluent to give the pure bromo-[4-(tetrahydro-pyran-4-sulfonyl)-phenyl]-acetic acid methyl ester (0.75 gm).
