Reaction Steps

In a similar manner to that described in example 196, from ethyl 7-[(4-fluorophenyl)methyl]-4-hydroxy-2-oxo-1-(2,2,2-trifluoroethyl)-1,2-dihydro-1,5-naphthyridine-3-carboxylate (23 mg, 0.0542 mmol) and 1-(3-aminopropyl)-2-pyrrolidinone (0.05 mL) was prepared 7-[(4-fluorophenyl)methyl]-4-hydroxy-2-oxo-N-[3-(2-oxo-1-pyrrolidinyl)propyl]-1-(2,2,2-trifluoroethyl)-1,2-dihydro-1,5-naphthyridine-3-carboxamide (15 mg, 54% yield) as a white solid after purification by reverse phase HPLC. 1H NMR (CDCl3) δ 10.05 (br s, 1 H), 8.59 (s, 1 H), 7.38 (s, 1 H), 7.16-7.13 (m, 2 H), 7.05-7.01 (m, 2 H), 4.86 (br s, 2 H), 4.14 (s, 2 H), 3.49-3.37 (m, 6 H), 2.40 (m, 2 H), 2.04 (m, 2 H), 1.87 (m, 2 H); MS m/z 521 (M+1).
