Participants

Reaction Steps

2-(((4-Methoxy-3-methyl-2-pyridinyl)methyl)thio)-6-methyl-5-(2,2,2-trifluoroethoxy)-3H-imidazo[4,5-b]pyridine (270 mg, 0.68 mmol) was dissolved in a mixture of methanol (2 ml) and toluene (18 ml), and a solution of metachloroperbenzoic acid (162 mg) in a mixture of methanol (0.5 ml) of toluene (0.5 ml) were added dropwise at −40° C. under nitrogen flow. After stirred at −20° C. to −40° C. for 2 hours, a sodium bicarbonate solution was added, the mixture was extracted with chloroform (30 ml), and dried over sodium sulfate. The solvent was evaporated, and the solid was precipitated from a mixture of chloroform and n-hexane to yield the title compound (263 mg, 0.63 mmol, 93%) as a purple gray solid.
