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 4-methyl-2-(5-oxo-1H-1,2,4-triazol-4(5H)-yl)thiazole-5-carboxylic acid to react with pyridin-3-ylmethanamine, the title compound was obtained as a white solid in 65% yield: mp 278-279° C. (ethyl acetate/hexane); 1H NMR (300 MHz, DMSO-d6) δ 8.87 (t, J=5.8 Hz, 1H), 8.61 (s, 1H), 8.53-8.48 (m, 1H), 8.45-8.39 (m, 1H), 7.72-7.65 (m, 1H), 7.37-7.29 (m, 1H), 4.39 (d, J=5.8 Hz, 2H), 2.53 (s, 3H); 13C NMR (75 MHz, DMSO-d6) δ 161.6, 151.9, 151.8, 149.4, 148.6, 135.7, 135.2, 133.4, 123.9, 122.3, 41.0, 17.4; MS (ES+) m/z 317.2 (M+1).
