Reaction Steps

The product was prepared in the same manner as described in example 44d using 2-(6-fluoropyridin-2-yl)-[1,2,4]triazolo[1,5-a]pyridin-7-amine (350 mg, 1.53 mmol) and 4-(ethoxycarbonyl)-1-methyl-1H-pyrazole-5-carboxylic acid (363 mg, 1.83 mmol) as starting materials. The reaction affords 5-[2-(6-fluoro-pyridin-2-yl)-[1,2,4]triazolo[1,5-a]pyridin-7-ylcarbamoyl]-1-methyl-1H-pyrazole-4-carboxylic acid ethyl ester (253.1 mg, 40.5%) as white solid. mp.: 290° C., MS: m/z=410.0 (M+H+).
