Product 1

HCID 685159425-Bromo-2-methanesulfonyl-1,3-dimethyl-benzeneYield 50%

Procedure

Dissolve 5-bromo-1,3-dimethyl-2-methylsulfanyl-benzene (555 mg, 2.42 mmol) in methanol (30 mL) and treat with oxone (6.0 g, 9.8 mmol). Stir the mixture at ambient temperature for 1 hour. Filter the suspension through silica gel and elute with CH2Cl2 (100 mL). Evaporate the filtrate to give 316 mg (50%) of the title compound.
