To a solution of 10.75 g (23.86 mmol) of 9-(4-methoxy-benzylamino)-4-oxo-2-pyrimidin-4-yl-5,6,8,9-tetrahydro-4H-1,4a,7-triaza-benzocycloheptene-7-carboxylic acid ethyl ester acetonitrile/water (160/80 mL) was added 26.16 g (47.73 mmol) of ammonium cerium nitrate. The reaction was stirred at room temperature for 2 hours. 13.08 g (23.86 mmol) of ammonium cerium nitrate was added and the reaction was stirred at room temperature for 0.5 hours. After an acido-basic work-up and extraction with dichloromethane, the organic phase was washed with a saturated solution of sodium chloride, dried over sodium sulfate and concentrated to afford 5.15 g (65%) of a powder.
