Reaction Steps

This compound was prepared from ethyl 7-[(4-fluorophenyl)methyl]-4-hydroxy-2-oxo-1-[2-oxo-2-(1-pyrrolidinyl)ethyl]-1,2-dihydro-1,5-naphthyridine-3-carboxylate and (±)-2-amino-1-propanol employing methods similar to those those described in Example 9 and was purified by reverse phase preparative HPLC (C-18 stationary phase; 10-100% CH3CN/water/0.1% formic acid mobile phase). The product was obtained as a white solid: 1H NMR (CDCl3) δ 10.16 (1H, d, J=8 Hz), 8.54 (1H, s), 7.15 (2H, dd, J=8.5, 5.3 Hz), 7.04 (1H, s), 7.02 (2H, t, J=8.5 Hz), 4.90 (1H, d, J=17 Hz), 4.83 (1H, d, J=17 Hz), 4.27 (1H, m), 4.11 (2H, s), 3.76 (1H, m), 3.66 (1H, m), 3.50-3.44 (4H, m), 2.24 (1H, br), 2.05 (2H, m, J=7 Hz), 1.89 (2H, m, J=7 Hz), 1.29 (3H, d, J=7 Hz); HRMS calcd for C25H27FN4O5+H+: 483.2044. Found: 483.2047.
