実験手順

A mixture of 1-methyl-5-(2-(pyridin-3-yl)-[1,2,4]triazolo[1,5-a]pyridin-7-ylcarbamoyl)-1H-pyrazole-4-carboxylic acid (100 mg, 223 μmol), 3-fluoroazetidine hydrochloride (74.7 mg, 669 μmol), propylphosphonic anhydride (50% in ethyl acetate, 329 μl, 558 μmol) and N,N-diisopropylethylamine (228 μl, 1.34 mmol) in tetrahydrofurane (7 ml) is stirred for 18 hours room temperature. The solvent is evaporated and the residue triturated with sat. aqueous sodium bicarbonate solution. The solid is collected by filtration, washed with water and dried affording 4-(3-fluoroazetidine-1-carbonyl)-1-methyl-N-(2-(pyridin-3-yl)-[1,2,4]triazolo[1,5-a]pyridin-7-yl)-1H-pyrazole-5-carboxamide (36 mg, 37.3%) as a light brown solid. mp.: 247-9° C. MS: m/z=421.1 (M+H+).
