実験手順
Following the procedure as described in Preparation 16, making variations as required to replace ethyl 4-methyl-2-(5-oxo-1H-1,2,4-triazol-4(5H)-yl)thiazole-5-carboxylate with 1-(5-acetyl-4-methylthiazol-2-yl)imidazolidin-2-one to react with 4-fluorobenzyl bromide, the title compound was obtained as a yellow solid in 98% yield: 1H NMR (300 MHz, CDCl3) δ 7.32-7.22 (m, 2H), 7.07-6.97 (m, 2H), 4.45 (s, 2H), 4.10-4.04 (m, 2H), 3.48-3.37 (m, 2H), 2.67 (s, 3H), 2.38 (s, 3H); MS (ES+) m/z 334.1 (M+1).
