실험 절차

4.45 g of (RS)-7-[4,5-bis(4-chlorophenyl)-2-oxazolyl]-2-methylheptanenitrile in 40 cm3 of dimethylformamide are treated with twice 2.1 g of sodium azide and twice 4.4 g of triethylamine hydrochloride under the (time and temperature) conditions defined in Example 1. After treatment, the product of the reaction is chromatographed on a column 2.8 cm in diameter containing 115 g of silica gel (50 to 200μ). The column is eluted with 1.2 liters of diisopropyl ether and then with 2.8 liters of a diisopropyl ether/ethyl acetate (80:20 by volume) mixture, collecting 200 cm3 fractions. The fractions from the last eluent mixture are concentrated to dryness under reduced pressure (0.2 kPa). 2.7 g (55%) of (RS)-5-{7-[4,5-bis(4-chlorophenyl)-2-oxazolyl]-2-heptyl}-1H-tetrazole are obtained in the form of white crystals, melting point 144° C.
