실험 절차

To a solution of 2-(4-amino-2-oxopyridin-1(2H)-yl)-N-benzyl-4-methylthiazole-5-carboxamide (0.14 g, 0.41 mmol) in N,N-dimethylformamide (10 mL) was added 2-chloroethyl isocyanate (0.05 mL, 0.58 mmol) at ambient temperature. The resulting reaction mixture was heated at 80-90° C. for 7 hours. Potassium carbonate (0.10 g, 0.72 mmol) was added and the reaction mixture was heated for 18 hours. The solvent was removed in vacuo, and the residue was purified by column chromatography to afford the title compound in 6% yield (0.01 g): mp>300° C.; 1H NMR (300 MHz, DMSO-d6) δ 8.76 (t, J=6.0 Hz, 1H), 8.56 (d, J=8.4 Hz, 1H), 7.64-7.17 (m, 7H), 6.08 (d, J=2.1 Hz, 1H), 4.38 (d, J=6.0 Hz, 2H), 3.85-3.79 (m, 2H), 3.42-3.37 (m, 2H), 2.60 (s, 3H); 13C NMR (75 MHz, DMSO-d6) δ 161.9, 160.7, 157.8, 153.8, 150.7, 150.4, 139.9, 130.9, 128.7, 127.7, 127.2, 123.7, 101.4, 98.8, 44.3, 43.1, 36.5, 17.5; MS (ES+) m/z 410.2 (M+1).
