Procedure

To a mixture of N-isopropyl-1-[3-(4-methylthiophenyl)phenyl]-1,4-dihydro[1,8]naphthyridin-4-one-3-carboxamide from Example 22 in tetrahydrofuran (24 ml/mmol), methanol (12 ml/mmol), and water (12 ml/mmol), was added oxone (2.24 eq) and the resulting mixture was stirred at room temperature for 2 hours. The mixture was quenched with saturated aqueous sodium bicarbonate and partitioned between ethyl acetate and water. The crude product from the organic phase was chromatographed on silica gel eluting with 30% ether in methylene chloride to afford the title compound as a white solid.
