Versuchsvorschrift

(±)-3-[3-(2-Fluoro-4-methoxy-phenyl)-4-methyl-2-oxo-7-phenylamino-3,4-dihydro-2H-pyrimido[4,5-d]pyrimidin-1-yl]-benzonitrile (0.80 g; 1.67 mmol) (from Example 9b supra) was dissolved in dimethyl sulfoxide (25 mL). Most of the material went into solution. Aqueous sodium hydroxide (1.0 N; 3.34 mL; 3.34 mmol) was added followed by hydrogen peroxide (30% in water; 0.51 mL, 4.99 mmol) at room temperature. After stirring for 45 minutes, water was added and a white solid precipitated out of solution. The solid was collected, washed with water and dried. Dissolution of the solid required significant volumes of dichloromethane-methanol-acetonitrile. The solvent mixture was then distilled off until solid began to crystallize out of solution. Cooling and filtration gave (±)-3-[3-(2-fluoro-4-methoxy-phenyl)-4-methyl-2-oxo-7-phenylamino-3,4-dihydro-2H-pyrimido[4,5-d]pyrimidin-1-yl]-benzamide as a white solid. (Yield 0.56 g; 67.6%).
