Reaction Steps

A solution of 89 g (0.352 mol) of 2-(4-chlorophenylethyl)-2-pentyl-oxirane, 26.5 g (0.384 mol) of 1,2,4-triazole, 3.5 g (0.0875 mol) of sodium hydroxide, 1.2 ml of water and a spatula tipful of α,α'-azoisobutyronitrile in 175 ml of N-methylpyrrolidone is heated at 120° C. for 4 hours. After this the mixture is cooled to room temperature and concentrated by stripping off the solvent under reduced pressure, the remaining residue is dissolved in ethyl acetate and washed three times with water, the organic phase is dried over sodium sulphate and the solvent is removed under reduced pressure. The residue is purified by column chromatography (silica gel; dichloromethane:ethyl acetate=1:1). In this manner 53.2 g (47.0% of theory) of 1-(4-chlorophenyl)-3-(1,2,4-triazol-1-yl-methyl)-3-octanol are obtained in the form of a yellow oil.
