Versuchsvorschrift

8.1 g (0.0633 mol) of 4-chlorophenol were added to a solution of 0.32 g (0.014 mol) of sodium in 100 ml of absolute ethanol. 10.3 g (0.0488 mol) of 2-(methoxy-tert.-butyl)-2-(1,2,4-triazol-1-yl-methyl)-oxirane, dissolved in 300 ml of absolute ethanol, were added, and the reaction mixture was heated under reflux for 48 hours. The reaction mixture was allowed to cool and was concentrated. The residue was taken up in ethyl acetate, and the solution was washed once with water, once with 1N sodium hydroxide solution, again with water, thereafter with 1N hydrochloric acid and 1N sodium hydroxide solution, again with water, and finally with saturated sodium chloride solution. The organic phase was dried over sodium sulphate, and concentrated. 10.7 g (64.6% of theory) of 2-(4-chlorophenoxymethyl)-3,3-dimethyl-4-methoxy-1-(1,2,4-triazol-1-yl)-butan-2-ol of refractive index nD20 =1.531 were obtained.
