Participants

Reaction Steps

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 cyclopropylethanamine, the title compound was obtained as a colorless solid in 76% yield: mp 240-242° C. (ethyl acetate/hexanes); 1H NMR (300 MHz, DMSO-d6) δ 11.56 (br s, 1H), 8.58 (d, J=8.0 Hz, 1H), 8.26 (t, J=5.6 Hz, 1H), 6.25 (dd, J=8.0, 2.5 Hz, 1H), 5.81 (d, J=2.5 Hz, 1H), 3.05 (m, 2H), 2.51 (s, 3H), 1.05-0.92 (m, 1H), 0.43-0.36 (m, 2H), 0.20-0.15 (m, 2H); 13C NMR (75 MHz, DMSO-d6) δ 167.9, 161.8, 161.6, 153.9, 149.7, 132.6, 124.0, 104.3, 98.0, 43.9, 17.4, 11.4, 3.7; MS (ES+) m/z: 306.2 (M+1).
