Reaction Steps
2,4-Dichloro-3-(4,5-dihydro-4-methyl-5-oxo-1H-tetrazol-1-yl)benzoic acid (3.42 g) and thionylchloride (4.22 g) were added to 1,2-dichloroethane (50 ml) The mixture, after adding several drops of N,N-dimethylformamide, was refluxed upon heating for 4 hours. After cooling, the solvent was distilled off to obtain crude 2,4-dichloro-3-(4,5-dihydro-4-methyl-5-oxo-1H-tetrazol-1-yl)benzoyl chloride (3.65 g).
