4-(4-Fluorobenzyl)-N-(4-(2-methyl-1H-imidazol-1-yl)phenyl)-7,8-dihydro-5H-thiopyrano[4,3-d]pyrimidin-2-amine (103 mg, 0.24 mmol) was dissolved in DCM (3 mL). mCPBA (61.8 mg, 0.36 mmol) was added and the reaction was stirred at rt for 2 h. Water was added and the product was obtained by separating the organic phase and evaporating the solvent. The crude product was purified using preparative HPLC yielding 4-(4-fluorobenzyl)-N-[4-(2-methyl-1H-imidazol-1-yl)phenyl]-7,8-dihydro-5H-thiopyrano[4,3-d]pyrimidin-2-amine 6-oxide (21.0 mg, 18.9%). MS (ES+) m/z 448.1 (M+H)+
