Reaction Steps

The method described in Part E of Example 12 was used to treat 1-{[3-(4-fluorophenyl)isoxazol-5-yl]methyl}-2-propyl-1H-imidazo[4,5-c][1,5]naphthyridine (1.08 g, 2.79 mmol) with mCPBA (1.1 g of 75% pure material followed by 0.35 g) with the modification that the trituration of the crude product was carried out with diethyl ether. 1-{[3-(4-Fluorophenyl)isoxazol-5-yl]methyl}-5-oxido-2-propyl-1H-imidazo[4,5-c][1,5]naphthyridine was obtained as a white solid.
