m-Chloroperbenzoic acid → 4-{5-[5-(3-Chloro-phenyl)-[1,2,4]oxadiazol-3-ylmethylsulfanyl]-4-methyl-4H-[1,2,4]triazol-3-yl}-pyridine 1-oxide

Participants

Reaction Steps

4-{5-[5-(3-Chloro-phenyl)-[1,2,4]oxadiazol-3-ylmethylsulfanyl]-4-methyl-4H-[1,2,4]triazol-3-yl}-pyridine and wet 57%-86% MCPBA (52.4 mg, 0.20-0.30 mmol) were dissolved in dichloromethane (4 ml) and stirred for 16 h. The reaction mixture was purified via reversed phase preparative LC to give the title compound (7.5 mg, 8%). 1H NMR (CDCl3), δ (ppm): 8.33 (d, 2 H), 8.06 (m, 1 H), 7.96 (m, 1 H), 7.67 (d, 2 H), 7.57 (m, 1 H), 7.46 (apparent t, 1 H), 4.60 (s, 2 H), 3.71 (s, 3 H).
