Procedure

Following the procedure as described in Example 19, making variation as required to replace 4-(trifluoromethyl)benzyl bromide with 1-(bromomethyl)-4-fluorobenzene to react with ethyl 4-methyl-2-(5-oxo-1H-1,2,4-triazol-4(5H)-yl)thiazole-5-carboxylate, the title compound was obtained as a white solid in 84% yield: 1H NMR (300 MHz, CDCl3) δ 8.27 (s, 1H), 7.47-7.30 (m, 2H), 7.11-6.97 (m, 2H), 4.98 (s, 2H), 4.32 (q, J=7.1 Hz, 2H), 2.65 (s, 3H), 1.34 (t, J=7.1 Hz, 3H); MS (ES+) m/z 363.1 (M+
