4-(Ethoxycarbonyl)-1-methyl-1H-pyrazole-5-carboxylic acid → 5-[2-(2-methoxy-phenyl)-[1,2,4]triazolo[1,5-a]pyridin-7-ylcarbamoyl]-1-methyl-1H-pyrazole-4-carboxylic acid ethyl ester

Reaction Steps

The product was prepared in the same manner as described in example 28 using 2-(2-methoxyphenyl)-[1,2,4]triazolo[1,5-a]pyridin-7-amine (365 mg, 1.52 mmol) and 4-(ethoxycarbonyl)-1-methyl-1H-pyrazole-5-carboxylic acid (331 mg, 1.67 mmol) as starting material. The reaction affords 5-[2-(2-methoxy-phenyl)-[1,2,4]triazolo[1,5-a]pyridin-7-ylcarbamoyl]-1-methyl-1H-pyrazole-4-carboxylic acid ethyl ester (410 mg, 64.2%) as white solid. MS: m/z=421.1 (M+H+).
