m-Chloroperbenzoic acid → [6-(Methylsulfinyl)-4-pyrimidinyl]acetonitrile

To a suspension of [6-(methylthio)-4-pyrimidinyl]acetonitrile (Intermediate 15, 292 mg, 1.767 mmol) in DCM (15 mL) was added 3-chloroperoxybenzoic acid (457 mg, 2.65 mmol) at 0° C. The reaction mixture was allowed to warm to room temperature and kept stirring for 3 hours. The reaction mixture was quenched with saturated sodium thiosulfate solution (10 mL) and vigorously stirred for 30 minutes, then treated with DCM (75 mL). The reaction mixture was partitioned between DCM and water. The organic layer was washed with saturated ammonium carbonate solution, water and brine sequentially, then dried over sodium sulfate, concentrated under pressure to give the title compound as a brown solid (150 mg);
