実験手順
A solution of 2-phenyl-[1,2,4]triazolo[1,5-a]pyridin-7-ylamine (1.534 g, 7.3 mmol), 4-(methoxycarbonyl)-1-methyl-1H-pyrazole-5-carboxylic acid (1.61 g, 8.76 mmol), propylphosphonic anhydride (50% in ethyl acetate, 10.7 ml, 18.2 mmol) and diisopropylethylamine (5.1 ml, 29.2 mmol) in tetrahydrofurane (54 ml) is stirred at 70° C. for 1.25 hr giving a white suspension. The cooled suspension is poured in sat. aqueous sodium bicarbonate solution (200 ml), stirred at room temperature for 15 min and the solid is collected by filtration, washed with water and dried affording methyl 1-methyl-5-(2-phenyl-[1,2,4]triazolo[1,5-a]pyridin-7-ylcarbamoyl)-1H-pyrazole-4-carboxylate (2.596 g, 94.5%) as a white solid. mp.: 243-7° C. MS: m/z=377.2 (M+H+).
