4-(1H-1,2,4-triazol-1-yl)benzoic acid (100 mg, 0.529 mmol) in sulfurous dichloride (2 ml) was refluxed at 110° C. for 2 h. After the excess SOCl2 was removed, the residue was dried in vacuo to give 4-(1H-1,2,4-triazol-1-yl)benzoyl chloride (110 mg, 0.529 mmol, 100% yield) as a white solid which was used in subsequent reactions without further purification.
