Reaction Steps

Add a suspension of oxone®(4.97 g, 8.1 mmol) in 10 mL water to a solution of 5-bromo-2-methylsulfanyl-pyridine (1.1 g, 5.4 mmol) in 10 mL methanol, stir at r.t. for 1 h and remove methanol under vacuum. Extract the aqueous residue with dichloromethane, dry the organic extracts over sodium sulfate, filtrate and concentrate under reduced pressure to obtain 1.24 g of 5-bromo-2-methanesulfonyl-pyridine. MS (m/e): 237 (M+H).
