Procedure
To a stirred solution of 2-(1H-tetrazol-1-yl)acetic acid 3 (1 gm, 7.81 mmol) in benzene (20 mL) was added oxalyl chloride (1.5 g, 11.81 mmol) and a catalytic amount of DMF. The reaction mixture was stirred at room temperature for 3 hrs. The reaction mixture was concentrated under vacuum and the crude acid chloride 4 obtained was used for the next step without any purification.
