Procedure

To a solution of N-cyclopropyl-1-[3-(4-ethylthiophenyl)phenyl]-1,4-dihydro[1,8]naphthyridin-4-one-3-carboxamide from Example 18, in a 1:1 mixture of methylene chloride and methanol (9 ml/mmol), was added at 0° C. magnesium monoperoxyphthalate hexahydrate (MMPP, 0.5 molareq) and the resulting mixture was stirred in the cold for 2 hours. The mixture was quenched with saturated aqueous sodium bicarbonate and partitioned between methylene chloride and water. The crude product from the organic phase was chromatographed on silica gel eluting with a 90:9:1 mixture of methylene chloride, ethanol and 28% aqueous ammonium hydroxide to afford the title compound as a solid.
