Participants

Reaction Steps

Following the procedure as described in Example 3, making variations only as required to use 2-hydroxy-3-(trifluoromethyl)pyridine in place of 4-aminopyridin-2(1H)-one to react with N-benzyl-2-bromo-4-methylthiazole-5-carboxamide, the title compound was obtained as a white solid in 37% yield: mp 203-204° C.; 1H NMR (300 MHz, CDCl3) δ 9.01 (d, J=7.2 Hz, 1H), 7.87 (d, J=7.2 Hz, 1H), 7.36-7.23 (m, 5H), 6.53 (t, J=7.2 Hz, 1H), 6.10 (s, 1H), 4.57 (d, J=5.4 Hz, 2H), 2.69 (s, 3H); 13C NMR (75 MHz, CDCl3) δ 161.7, 156.6, 152.2, 152.1, 139.3, 139.2, 137.4, 135.1, 128.9, 128.8, 127.8, 123.8, 121.9, 106.0, 44.2, 17.2; MS (ES+) m/z 394.2 (M+1).
