実験手順

In a similar manner to that described in example 196, from ethyl 1-(4-fluorophenyl)-7-[(4-fluorophenyl)methyl]-4-hydroxy-2-oxo-1,2-dihydro-1,5-naphthyridine-3-carboxylate (22 mg, 0.0504 mmol) and methylamine (0.1 mL of a 8 M solution in ethanol) was prepared 1-(4-fluorophenyl)-7-[(4-fluorophenyl)methyl]-4-hydroxy-N-methyl-2-oxo-1,2-dihydro-1,5-naphthyridine-3-carboxamide (6 mg, 29% yield) as a tan solid after purification by reverse phase HPLC. 1H NMR (CDCl3) δ 9.87 (br s, 1 H), 8.52 (s, 1 H), 7.30-7.24 (m, 2 H), 7.20-7.16 (m, 2 H), 7.01-6.91 (m, 4 H), 6.71 (s, 1 H), 3.94 (s, 2 H), 2.96 (d, J=4.8 Hz, 3 H); MS m/z 422 (M+1).
