実験手順

To a solution of 5-[2-(3-methoxy-phenyl)-[1,2,4]triazolo[1,5-a]pyridin-7-ylcarbamoyl]-1-methyl-1H-pyrazole-4-carboxylic acid (4.0 g, 10.2 mmol) in DMF (50 ml) were added HATU (8.5 g, 22 mmol), azetidine hydrochloride (1.05 g, 93.5 mmol) and DIPEA (7.5 ml, 40 mmol) at 0° C. The resultant reaction mixture was stirred at 25° C. for 16 h. The mixture was diluted with water (100 ml) and stirred for 15 min. The resultant precipitated solid was filtered, washed thoroughly with water, and dried azeotropically with toluene followed by vacuum to yield 4-(azetidine-1-carbonyl)-2-methyl-2H-pyrazole-3-carboxylic acid [2-(3-methoxy-phenyl)-[1,2,4]triazolo[1,5-a]pyridin-7-yl]-amide as off-white solid (1.9 g, 44%). LC-MS: m/z=432.4 [M+H]+.
