Procedure

A mixture of 5-(2-(ethyl(methyl)amino)-[1,2,4]triazolo[1,5-a]pyridin-7-ylcarbamoyl)-1-methyl-1H-pyrazole-4-carboxylic acid (144 mg, 419 μmol), morpholine (365 mg, 4.19 mmol), propylphosphonic anhydride (50% in ethyl acetate, 618 μl, 1.05 mmol) and N,N-diisopropylethylamine (214 μL, 1.26 mmol) in tetrahydrofuran (7.00 ml) was refluxed for 2.5 days (weekend). The solvent was evaporated, the residue was triturated with sodium hydrogencarbonate solution. The precipitated solid was filtered off, washed with water and dried affording 2-methyl-4-(morpholine-4-carbonyl)-2H-pyrazole-3-carboxylic acid [2-(ethyl-methyl-amino)-[1,2,4]triazolo[1,5-a]pyridin-7-yl]-amide (141 mg, 81.5%) as a white solid. mp: 167-169° C., MS: m/z=413.4 (M+H+)
