m-Chloroperbenzoic acid → 2-Chloro-5-methoxy-3-methylpyridine 1-oxide

참여 물질

반응 단계

3-Chloroperoxybenzoic acid (70%, 695 mg, 2.82 mmol) was added to a solution of 2-chloro-5-methoxy-3-methylpyridine (370 mg, 2.35 mmol) in dichloromethane (10 mL). After stirring for 18 hours at room temperature, the reaction mixture was concentrated in vacuo and purified via silica gel chromatography (Gradient: 0% to 10% methanol in ethyl acetate) to afford the product as a white solid. Yield: 370 mg, 2.13 mmol, 91%. 1H NMR (400 MHz, CD3OD) δ 8.14 (d, J=2.5 Hz, 1H), 7.23 (d, J=2.3 Hz, 1H), 3.88 (s, 3H), 2.44 (s, 3H).
