Sodium Sulfite → 1-Bromo-4-methanesulfonyl-2-methylbenzene

Participants

Reaction Steps

To a heterogenous solution of (4-bromo-3-methylphenyl)(methyl)sulfane (2.17 g, 9.99 mmol) in 55 mL of 10/1 MeOH/water at 0° C. was added oxone (6.14 g, 9.99 mmol). The solution was allowed to warm up to RT and stirred overnight. Saturated sodium sulfite (aq.) was added and the mixture was extracted with DCM (3×). The combined organic layers were washed with water and NaCl (sat.), dried over sodium sulfate, filtered and concentrated to afford 2.30 g of 1-bromo-2-methyl-4-(methylsulfonyl)benzene 2.30 g as a white solid.
