Versuchsvorschrift

To a solution of 2-(4-amino-2-oxopyridin-1(2H)-yl)-N-benzyl-4-methylthiazole-5-carboxamide (0.30 g, 0.88 mmol) and trifluoroacetic acid (15 mL) in chloroform (20 mL) was added benzaldehyde (0.10 mL, 0.98 mmol). The reaction mixture was stirred for 15 minutes at ambient temperature, then triethylsilane (0.15 mL, 1.00 mmol) was added. The reaction mixture was kept stirring for 2 hours at ambient temperature, then another portion of benzaldehyde (0.10 mL, 0.98 mmol) and triethylsilane (0.15 mL, 1.00 mmol) was added. The reaction mixture was kept stirring for another 2 hours at ambient temperature. The solvent was removed in vacuo, and the residue was washed with saturated aqueous sodium bicarbonate solution, water and t-butylmethyl ether to afford the title compound (0.30 g, 79%): mp 253-255° C.; 1H NMR (300 MHz, DMSO-d6) δ 8.68 (t, J=5.7 Hz, 1H), 8.39 (d, J=7.8 Hz, 1H), 7.87 (s, 1H), 7.44-7.21 (m, 10H), 6.21 (d, J=7.8 Hz, 1H), 5.31 (s, 1H), 4.36 (d, J=5.7 Hz, 2H), 4.31 (d, J=4.5 Hz, 2H), 2.50 (s, 3H); 13C NMR (75 MHz, DMSO-d6) δ 162.1, 160.9, 155.9, 154.5, 150.2, 140.0, 138.3, 130.6, 128.9, 128.7, 127.7, 127.6, 127.1, 122.8, 103.6, 88.6, 46.0, 43.0, 17.5; MS (ES+) m/z 431.2 (M+1).
