Reaction Conditions

Reaction Steps

To a cooled (0° C.) solution of 4-((2-cyclopropylpropan-2-yl)amino)-2-(methylthio)pyrimidine-5-carboxamide (390 mg, 1.46 mmol) in THF (6 mL) was added mCPBA (447 mg, 2.2 mmol) portion-wise. The reaction mixture was stirred for 0.5 h at 0° C. The mixture was concentrated under vacuum and purified by silica gel column chromatography (2.5%-10% DCM in methanol) to give a mixture of 4-((2-cyclopropylpropan-2-yl)amino)-2-(methylsulfinyl)pyrimidine-5-carboxamide and 4-((2-cyclopropylpropan-2-yl)amino)-2-(methylsulfonyl)pyrimidine-5-carboxamide (382 mg, 1.32 mmol, 90% yield). MS (ESI) m/z 299.1 [M+H]+ and 283.1 [M+H]+.
