Participants

Reaction Steps

2 Drops of DMF are added to a solution of 4-[2-(cyclopropanecarbonyl-amino)-[1,2,4]triazolo[1,5-a]pyridin-5-yl]-benzoic acid (1 eq) obtained by Method A using 4-carboxyphenylboronic acid in DCM under N2 atmosphere. Then oxalyl chloride (2 eq) is added dropwise to this resulting solution (gas release). The mixture is stirred at room temperature for 2 hours. After completion of the reaction by LCMS, the solvent is removed. The crude acid chloride is used without further purification in next step.
