2-(1-(4-fluorobenzyl)-5-oxo-1H-1,2,4-triazol-4(5H)-yl)-4-methylthiazole-5-carboxylic acid → 2-(3-(4-Chlorobenzyl)-2-oxoimidazolidin-1-yl)-4-methylthiazole-5-carboxamide

Participants

Reaction Steps

Following the procedure as described in Example 1, making variations as required to replace 2-(1-(4-fluorobenzyl)-5-oxo-1H-1,2,4-triazol-4(5H)-yl)-4-methyl-thiazole-5-carboxylic acid with 2-(3-(4-chlorobenzyl)-2-oxoimidazolidin-1-yl)-4-methylthiazole-5-carboxylic acid, the title compound was obtained as a colorless solid: mp >200° C.; 1H NMR (300 MHz, DMSO-d6) δ 7.46-7.37 (m, 6H), 4.47 (s, 2H), 4.03 (br s, 2H), 3.49-3.37 (m, 2H), 2.50 (s, 3H); MS (ES+) m/z 350.8 (M+1).
