Reaction Steps

5-{2,4-Dichloro-3-[2-(1H-tetrazol-1-yl)ethyloxy]-benzoyloxy}-1,3-dimethylpyrazole (0.65 g) was dissolved in acetonitrile (10 ml), triethylamine (0.33 g) and acetone cyanohydrin (40 mg) were added thereto and the mixture was stirred at room temperature for 12 hours. The solvent was distilled off, acidified by the addition of diluted hydrochloric acid and extracted with ethyl acetate (150 ml). The organic layer was washed with saturated brine and dried with anhydrous magnesium sulfate. Ethyl acetate was distilled off to obtain objective 4-{2,4-dichloro-3-[2-(1H-tetrazol-1-yl)ethoxy]benzoyl}-1,3-dimethyl-5-hydroxy-pyrazole (0.59 g).
