Reaction Steps

N-{3-[8-(2,6-difluorophenyl)-2-(methylthio)-7-oxo-5,6,7,8-tetrahydropyrimido[4,5-d]pyrimidin-4-yl]-4-methylphenyl}-3-thiophene-carboxamide (0.052 g, 0.1 mmol) was dissolved in a mixture of CH2Cl2 (10 mL) and DMF (0.5 mL). Then 3-chloroperoxybenzoic acid (50-60%) (0.03 g, ˜0.1 mmol) was added and the mixture stirred for 45 min at room temperature. Solvent was pumped off in vacuo to give the title compound plus a small amount of the corresponding sulfone. The mixture was used without further purification. LC-MS m/z 540 (M+H)+, 1.76 min (ret. time).
