4-(4-Fluorobenzyl)-N-(3-methoxy-4-(4-methyl-1H-imidazol-1-yl)phenyl)-7,8-dihydro-5H-thiopyrano[4,3-d]pyrimidin-2-amine (254 mg, 0.55 mmol) and meta-chloroperbenzoic acid (95 mg, 0.55 mmol) was slurrified in DCM (4 mL). Saturated NaHCO3 and water were added to the reaction mixture, the organic phase was separated and the solvent was evaporated. The crude product was purified on preparative HPLC yielding 4-(4-fluorobenzyl)-N-[3-methoxy-4-(4-methyl-1H-imidazol-1-yl)phenyl]-7,8-dihydro-5H-thiopyrano[4,3-d]pyrimidin-2-amine 6-oxide (49.0 mg, 18%).
