실험 절차
2,4-dichloro-3-[2-(1H-tetrazol-1-yl)ethoxy]benzoic acid (0.46 g) and thionyl chloride (0.36 g) were added in 1,2-dichloroethane (10 ml), two drops of DMF were added and the mixture was refluxed by heating for 3 hours. After cooling, the solvent was distilled off to obtain the desired 2,4-dichloro-3-[2-(1H-tetrazol-1-yl)ethoxy]benzoyl chloride (0.49 g).
