Procedure
A mixture of ethyl 7-(4-fluorobenzyl)-4-hydroxy-2-oxo-1-[2-(2-oxopyrrolidin-1-yl)ethyl]-1,2-dihydro-1,5-naphthyridine-3-carboxylate (30 mg, 0.066 mmol) and 2-[(2-aminoethyl)oxy]ethanol (100 μL) was heated in EtOH (3 mL) at 175° C. for 45 min. in a microwave. The reaction mixture was evaporated in vacuo and partitioned between 1N NaHSO4 and CH2Cl2. The aqueous phase was back-extracted with CH2Cl2 and the combined organic layers were dried over MgSO4, filtered, evaporated in vacuo and triturated with Et2O to provide the product as a white solid: 1H NMR (d6-DMSO) δ 10.35 (1H, t, J=5 Hz), 8.54 (1H, s), 8.09 (1H, s), 7.39 (2H, dd, J=5, 9 Hz), 7.11 (2H, t, J=9 Hz), 4.59 (1H, t, J=5 Hz), 4.36 (2H, t, J=6 Hz), 4.14 (2H, s), 3.33-3.56 (12H, m), 1.93 (2H, t, J=8 Hz), 1.74 (2H, t, J=7 Hz); ES+ MS: 513 (M+H+).
