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 (±)-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 14.5 (1H, br), 10.32 (1H, m), 8.54 (1H, s), 7.15 (2H, dd, J=8.5, 5.5 Hz), 7.08 (1H, s), 7.02 (2H, t, J=8.5 Hz), 4.88 (2H, m), 4.11 (2H, s), 4.05 (1H, m), 3.61 (1H, m), 3.51-3.44 (4H, m), 3.35 (1H, m), 2.20 (1H, d, J=4 Hz), 2.04 (2H, m, J=7 Hz), 1.89 (2H, m, J=7 Hz), 1.26 (3H, d, J=6 Hz); HRMS calcd for C25H27FN4O5+H+: 483.2044. Found: 483.2029.
