Procedure
In a similar manner to that described in example 196, from ethyl 1-ethyl-7-[(4-fluorophenyl)methyl]-4-hydroxy-2-oxo-1,2-dihydro-1,5-naphthyridine-3-carboxylate (30 mg, 0.081 mmol) and 2-aminoethanol (0.05 mL) was prepared 1-ethyl-7-[(4-fluorophenyl)methyl]-4-hydroxy-N-(2-hydroxyethyl)-2-oxo-1,2-dihydro-1,5-naphthyridine-3-carboxamide (18 mg, 58% yield) as a white solid after purification by reverse phase HPLC. 1H NMR (CDCl3) δ 10.47 (br s, 1 H), 8.53 (s, 1 H), 7.35 (s, 1 H), 7.17-7.13 (m, 2 H), 7.04-6.99 (m, 2 H), 4.20-4.13 (m, 4 H), 3.85 (m, 2 H), 3.63 (m, 2 H), 1.22 (m, 3 H); HRMS m/z calcd for C20H21FN3O4: 386.1510. Found: 386.1517.
