Procedure

To a mixture of N-isobutyl-1-{3-[6-(1-hydroxy-1-methylethyl)pyridin-3-yl]phenyl}-1,4-dihydro[1,8]naphthyridin-4-one-3-carboxamide from Example 46 in 13:1 methylene chloride/methanol (33 ml/mmol) at room temperature was added magnesium monoperoxyphthalate hexahydrate (MMPP, 1.1 molareq) and the resulting mixture was stirred at room temperature for 24 hours. The mixture was filtered through a bed of celite and the filtrate was washed with aqueous sodium carbonate, then water and dried. The crude product was chromatographed on silica gel eluting with 8% ethanol in ethyl acetate and the solid obtained was stirred at room temperature in ether for several hours and filtered to afford the title compound as a light pink solid.
