Reaction Conditions

Reaction Steps

A solution of m-chloroperbenzoic acid (160 mmol) in acetic acid (200 mL) was added dropwise to a solution of 3-methylisothiazolo[5,4-b]pyridine (107 mmol) in dichloromethane (200 mL). The reaction mixture was maintained for 6 h at 25° C. The reaction mixture was diluted with water (100 mL), the pH was adjusted to 8 with 10% sodium hydroxide, and the layers were separated. The aqueous layer was extracted with ethyl acetate (10×100 mL) and the combined organic layers were dried (magnesium sulfate) and concentrated to provide 3-methylisothiazolo[5,4-b]pyridine-N-oxide in 62% yield as a yellow solid.
