Participants

Reaction Steps

Following the procedure as described in Example 3, making variations only as required to use 3-methylpyrazin-2(1H)-one 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 5% yield: mp 186-187° C.; 1H NMR (300 MHz, CDCl3) δ 8.44 (s, 1H), 7.45-7.25 (m, 6H), 6.12 (s, 1H), 4.59 (d, J=5.7 Hz, 2H), 2.69 (s, 3H), 2.55 (s, 3H); 13C NMR (75 MHz, CDCl3) δ 161.6, 159.2, 153.4, 152.4, 152.0, 137.5, 128.8, 127.9, 127.8, 124.5, 123.5, 119.3, 44.2, 20.8, 17.3; MS (ES+) m/z 341.2 (M+1).
