Participants

Reaction Steps

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 3-(4-morpholinyl)-1-propanamine (0.357 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 a pale yellow solid: 1H NMR (300 MHz, DMSO-d6) δ ppm 1.68-1.76 (m, 2 H), 2.31-2.38 (m, 7 H), 2.78 (t, J=6.81 Hz, 2 H), 3.35-3.46 (m, 3 H), 3.55-3.62 (m, 5 H), 4.16 (s, 2 H), 4.22 (t, J=6.81 Hz, 2 H), 7.10-7.17 (m, 2 H), 7.38 (ddd, J=9.02, 5.79, 3.02 Hz, 2 H), 8.15 (s, 1 H), 8.50 (d, J=1.26 Hz, 1 H), 10.41 (d, J=3.93 Hz, 1 H); ES+ MS: 484 (M+H+).
