Propylphosphonic anhydride has been shown to be an effective reagent for the synthesis of substituted [1,2,4]triazolo[1,5-a]pyridines from the corresponding N′-hydroxy-N-formimidamides. The reactions worked under mild conditions and exhibited wide functional group tolerance, delivering the triazolopyridines in good to excellent yields and purities.
