Procedure

AIBN (1.35 mmol) was added to a solution of 6-chloro-3-methylisothiazolo[5,4-b]pyridine (13.5 mmol) and N-bromosuccinamide (27.1 mmol) in carbon tetrachloride (25 mL). The reaction mixture was heated at 80° C. for 6 h, allowed to cool to rt, and the precipitated solids were removed by filtration. The filtrate was concentrated to provide crude 3-(bromomethyl)-6-chloroisothiazolo[5,4-b]pyridine as yellow oil.
