Procedure

10.3 g (0.052 mole) of 3,3-dimethyl-2-hydroxy-2(1,2,4-triazol-1-yl-methyl)-tetrahydrofuran, 2.9 g (0.052 mole) of potassium hydroxide and 8.4 g (0.052 mole) of 4chlorobenzyl chloride are stirred in a mixture of 100 ml of dimethylsulphoxide and 6 ml of water at 30° C. for 2 hours. The reaction solution is then poured onto water and extracted with ethyl acetate. The organic phase is dried over sodium sulphate and concentrated. After trituration in n-hexane, the residue crystallizes. 6.6 g (39.5% of theory) of 1-(4-chlorophenyl)-2-(3,3-dimethyl-2-hydroxy-tetrahydrofuran-2-yl)-2-(1,2,4-triazol-1-yl)ethane of melting point 98° C. are obtained. ##STR98##
