Reaction Steps

This compound was prepared from ethyl 7-[(4-fluorophenyl)methyl]-4-hydroxy-2-oxo-1-[2-oxo-2-(1-piperidinyl)ethyl]-1,2-dihydro-1,5-naphthyridine-3-carboxylate and (±)-1-amino-2-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 10.32 (1H, m), 8.55 (1H, s), 7.16 (2H, dd, J=8.5, 5.5 Hz), 7.03 (2H, t, J=8.5 Hz), 6.97 (1H, s), 4.94 (2H, m), 4.11 (2H, s), 4.04 (1H, m), 3.62 (1H, m), 3.50 (2H, t, J=5.5 Hz), 3.44 (2H, t, J=5.5 Hz), 3.35 (1H, m), 2.21 (1H, d, J=4 Hz), 1.69 (2H, m), 1.54 (4H, m), 1.26 (3H, d, J=6 Hz); HRMS calcd for C26H29FN4O5+H+: 497.2200. Found: 497.2189.
