Reaction Steps

2-Phenyl-5-trifluoromethyl-oxazole-4-carboxylic acid (6-thiomorpholin-4-yl-pyridin-3-yl)-amide (30 mg, 0.07 mmol) was dissolved in 3 mL of methylene chloride, and cooled down to −78° C. One equivalent of 3-chloroperoxybenzoic acid (12 mg, 0.07 mmol) was added. The reaction mixture was warmed up to room temperature and stirred for 2 hours. The reaction mixture was concentrated under reduced pressure, and then purified by flash chromatography (Merck silica gel 60, 230-400 mesh, 0-20% methanol in methylene chloride for 25 min) to gave 2-phenyl-5-trifluoromethyl-oxazole-4-carboxylic acid [6-(1-oxo-1λ4-thiomorpholin-4-yl)-pyridin-3-yl]-amide as an off-white solid. LCMS calcd for C20H17F3N4O3S (m/e) 450, obsd 451 (M+H).
