Procedure

A solution of the crude 3-(bromomethyl)isothiazolo[5,4-b]pyridine (3.49 mmol) in dimethylsulfoxide (20 mL) was treated with water (4 mL) and the reaction mixture was heated at 80° C. for 1.5 h. The reaction mixture was diluted with water (100 mL), filtered through Celite, and was extracted with ethyl acetate (3×30 mL). The combined organic layers were washed with water, dried (magnesium sulfate), and concentrated to provide isothiazolo[5,4-b]pyridin-3-ylmethanol in 31% yield as yellow oil.
