Reaction Steps

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 (20 mg, 0.043 mmol) and N-(2-aminoethyl)acetamide (60 mg, 0.595 mmol), was prepared N-[2-(acetylamino)ethyl]-1-(4-fluorophenyl)-7-[(4-fluorophenyl)methyl]-4-hydroxy-2-oxo-1,2-dihydro-1,5-naphthyridine-3-carboxamide (12 mg, 57% yield) as a white solid after purification by reverse phase HPLC. 1H NMR (CDCl3) δ 10.17 (br s, 1 H), 8.54 (s, 1 H), 7.32-7.27 (m, 2 H), 7.22-7.18 (m, 2 H), 7.03-6.93 (m, 4 H), 6.74 (s, 1 H), 6.03 (br s, 1 H), 3.96 (s, 2 H), 3.58 (m, 2 H), 3.46 (m, 2 H), 1.97 (s, 3 H); MS m/z 493 (M+1).
