Participants

Reaction Steps

A solution of 1-(2-aminoethyl)-7-[(4-fluorophenyl)methyl]-4-hydroxy-N-[2-(4-morpholinyl)ethyl]-2-oxo-1,2-dihydro-1,5-naphthyridine-3-carboxamide (0.025 g, 0.052 mmol) and diisopropyl ethylamine (0.05 mL, 0.29 mmol) in DMF (5 mL) under nitrogen was treated with 4-morpholinecarbonyl chloride (0.008 mL, 0.068 mmol) at 40° C. for 1 h then 3½ h at ambient temperature. The reaction was concentrated in vacuo and the resulting residue was triturated with Et2O:MeOH, filtered, washed with 2:1 Et2O:MeOH, and dried in vacuo to provide the title compound as an off-white solid: 1H NMR (300 MHz, DMSO-d6) δ ppm 1.3 (s, 1 H), 3.10 (s, 2 H), 3.13-3.22 (m, 8 H), 3.27-3.33 (m, 1 H), 3.42-3.50 (m, 4 H), 3.55 (d, J=10.67 Hz, 2 H), 3.63-3.73 (m, 2 H), 3.78 (d, J=4.49 Hz, 1 H), 3.93-4.05 (m, 2 H), 4.14 (s, 2 H), 4.30 (t, J=6.67 Hz, 2 H), 7.11-7.19 (m, 2 H), 7.39-7.47 (m, 2 H), 8.34 (s, 1 H), 8.57 (d, J=1.12 Hz, 1 H), 9.88 (br. s., 1 H), 10.38-10.48 (m, 1 H); ES+ MS: 583 (M+H+).
