Versuchsvorschrift

A mixture of 7-(4-(azetidine-1-carbonyl)-1-methyl-1H-pyrazole-5-carboxamido)-[1,2,4]triazolo[1,5-a]pyridine-2-carboxylic acid (140 mg, 0.379 mmole), 3,3,3-trifluoropropan-1-amine (214 mg, 1.9 mmole), N-ethyldiisopropylamine (265 ul, 1.52 mmole) and 1-propanephosphonic acid cyclic anhydride (50% in ethyl acetate, 569 ul, 0.948 mmole) in tetrahydrofurane (7 ml) is stirred for 10 h at roomtemperature. The reaction mixture is poured on sat. aqueous sodium bicarbonate solution (60 ml) and extracted with ethyl acetate (2×50 ml). The combined organic layer is washed once with water, once with brine, dried with magnesium sulfate and the solvent is removed in vacuo. Purification of the residue by chromatography on a 12 g silica cartridge (eluent dichloromethane+2% methanol) affords 7-(4-(azetidine-1-carbonyl)-1-methyl-1H-pyrazole-5-carboxamido)-N-(3,3,3-trifluoropropyl)-[1,2,4]triazolo[1,5-a]pyridine-2-carboxamide (31 mg, 17.6%) as a white foam. MS: m/z=465.3 (M+H+).
