실험 절차

A solution of 1-(2-aminoethyl)-N-[2-(ethyloxy)ethyl]-7-[(4-fluorophenyl)methyl]-4-hydroxy-2-oxo-1,2-dihydro-1,5-naphthyridine-3-carboxamide (0.02 g, 0.047 mmol) and diisopropyl ethylamine (0.041 mL, 0.24 mmol) in DMF (5 mL) under nitrogen was treated with methyl chloroformate (0.0036 mL, 0.047 mmol) at ambient temperature. The reaction was concentrated in vacuo and the resulting residue treated with 1 N NaHSO4, filtered, then washed with 1 N NaHSO4 and Et2O before drying in vacuo to provide the title compound as an off-white solid: 1H NMR (300 MHz, DMSO-D6) δ ppm 1.1 (t, J=7.0 Hz, 3 H), 3.3 (m, 2 H), 3.4 (s, 3 H), 3.5 (m, 7 H), 4.1 (s, 2 H), 4.3 (t, J=6.0 Hz, 2 H), 7.1 (t, J=8.8 Hz, 2 H), 7.3 (m, 1 H), 7.4 (m, 2 H), 8.1 (s, 1 H), 8.5 (s, 1 H), 17.1 (s, 1 H); ES+ MS: 487 (M+H+).
