Reaction Steps

Following the procedure as described in Example 21, making variations as required to replace 4-methyl-2-(5-oxo-1-(4-(trifluoromethyl)benzyl)-1H-1,2,4-triazol-4(5H)-yl)thiazole-5-carboxylic acid with 2-(1-(4-fluorobenzyl)-5-oxo-1H-1,2,4-triazol-4(5H)-yl)-4-methylthiazole-5-carboxylic acid to react with thiazol-2-ylmethanamine hydrochloride, the title compound was obtained as a white solid in 66% yield: mp 189-190° C. (ethyl acetate/hexane); 1H NMR (300 MHz, CDCl3) δ 8.25 (s, 1H), 7.74 (br s, 1H), 7.40-7.31 (m, 3H), 7.06-6.97 (m, 2H), 6.78 (t, J=5.4 Hz, 1H), 4.97 (s, 2H), 4.92 (d, J=5.4 Hz, 2H), 2.67 (s, 3H); MS (ES+) m/z 431.1 (M+1).
