Versuchsvorschrift
The product was prepared in the same manner as described in example 66 using 4-(azetidine-1-carbonyl)-N-(2-bromo-[1,2,4]triazolo[1,5-a]pyridin-7-yl)-1-methyl-1H-pyrazole-5-carboxamide (150 mg, 371 μmol) and 2-methylpyridin-4-ylboronic acid (76.2 mg, 557 μmol) as starting materials. The crude material was applied on silicagel and purified by flash chromatography over a 20 g silicagel column using ethyl acetate/methanol 10% as eluent affording 4-(azetidine-1-carbonyl)-2-methyl-2H-pyrazole-3-carboxylic acid [2-(2-methyl-pyridin-4-yl)-[1,2,4]triazolo[1,5-a]pyridin-7-yl]-amide (34 mg, 22.0%) as an off-white solid. mp: 210-211° C., MS: m/z=417.4 (M+H+)
