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 (20 mg, 0.050mmol) and 2-amino-1-propanol (0.05 mL) was prepared 7-[(4-fluorophenyl)methyl]-4-hydroxy-N-(2-hydroxy-1-methylethyl)-2-oxo-1-(2,2,2-trifluoroethyl)-1,2-dihydro-1,5-naphthyridine-3-carboxamide(15 mg, 65% yield) as a white solid after purification by reverse phase HPLC. 1H NMR (CDCl3) δ 9.98 (d, J=7.6 Hz, 1 H), 8.58 (s, 1 H), 7.37 (s, 1 H), 7.15-7.12 (m, 2 H), 7.04-6.99 (m, 2 H), 4.82 (br s, 2 H), 4.26 (m, 1 H), 4.13 (s, 2 H), 3.78 (dd, J=10.8, 4 Hz, 1 H), 3.67 (dd, J=10.8, 6, 1 H), 1.30 (d, J=6.8 Hz, 3 H); MS m/z 454 M+1).
