Reaktionsschritte

Following the procedure as described in Example 1, making variations only as required to use 2-(4-hydroxy-2-oxopyridin-1(2H)-yl)-4-methylthiazole-5-carboxylic acid in place of 4-methyl-2-(2-oxo-4-phenylpyridin-1(2H)-yl)thiazole-5-carboxylic acid to react with (5-methylpyrazin-2-yl)methanamine, the title compound was obtained as a colorless solid in 14% yield: 1H NMR (300 MHz, DMSO-d6) δ 11.49 (s, 1H), 8.80 (t, J=5.2 Hz, 1H), 8.59 (d, J=7.8 Hz 1H), 8.44 (s, 2H), 6.26 (d, J=7.8 Hz, 1H), 5.81 (s, 1H), 4.47 (d, J=5.2 Hz, 2H), 2.52 (s, 3H), 2.43 (s, 3H); MS (ES+) m/z 358.1 (M+1).
