実験手順

A mixture of 1-methyl-5-(2-(pyrrolidin-1-yl)-[1,2,4]triazolo[1,5-a]pyridin-7-ylcarbamoyl)-1H-pyrazole-4-carboxylic acid (150 mg, 422 μmol), morpholine (368 μl, 4.22 mmol), propylphosphonic anhydride (50% in ethyl acetate, 622 μl, 1.06 mmol) and N,N-diisopropylethylamine (215 μl, 1.27 mmol) in tetrahydrofuran (6 ml) was stirred for 18 hours at 70° C. The solvent was evaporated, the residue was triturated with sodium hydrogencarbonate solution. The mixture was extracted with ethyl acetate, washed with water. The organic layer was separated, dried over magnesium sulfate, filtrated and evaporated affording 2-methyl-4-(morpholine-4-carbonyl)-2H-pyrazole-3-carboxylic acid (2-pyrrolidin-1-yl-[1,2,4]triazolo[1,5-a]pyridin-7-yl)-amide (109 mg, 60.8%) as a light yellow solid. mp: 194-197° C., MS: m/z=425.3 (M+H+).
