Procedure

A solution of ethyl 1-[2-(1,3-dioxo-1,3-dihydro-2H-isoindol-2-yl)ethyl]-7-[(4-fluorophenyl)methyl]-4-hydroxy-2-oxo-1,2-dihydro-1,5-naphthyridine-3-carboxylate (0.252 g, 0.49 mmol) in EtOH (15 mL) under nitrogen was treated with 1-(tetrahydro-2-furanyl)methanamine (0.252 mL, 2.44 mmol) for 15 min.@150° C. in a microwave vessel. The reaction was transferred to a test tube, diluted with EtOH (30 mL), and treated with hydrazine (0.4 mL, 13 mmol)@50° C. overnight. After the reaction was cooled to ambient temperature the resulting suspension was diluted with water (120 mL) and refrigerated overnight. The resulting suspension was filtered, washed with 2:1 water:EtOH and thoroughly dried under high vacuum to provide the title compound as an off-white solid: 1H NMR (300 MHz, DMSO-d6) δ ppm 1.49-1.61 (m, 1H), 1.80-2.00 (m, 3H), 2.78 (t, J=6.46 Hz, 2H), 3.25-3.41 (m, 1H), 3.49-3.59 (m, 1H), 3.68 (t, J=6.81 Hz, 1H), 3.75-3.86 (m, 1H), 3.95-4.05 (m, 1H), 4.16 (s, 2H), 4.18-4.26 (m, 2H), 7.14 (ddd, J=8.95, 6.91, 1.82 Hz, 2H), 7.35-7.43 (m, 2H), 8.15 (d, J=1.40 Hz, 1H), 8.51 (s, 1H), 10.44-10.53 (m, 1H); ES+ MS: 441 (M+H+).
