9.9 g (0.03 mol) of 4-tert.-butyl-6-(4-chlorophenyl)-5-(1,2,4-triazol-1-yl)-hex-1-in-4-ol are dissolved in 100 ml of methanol, and 9.2 g (0.036 mol) of iodine are introduced into the ice-cooled solution at the same time as 14.5 ml of 50% strength potassium hydroxide solution are being added dropwise. The mixture is stirred for a further 4 hours at room temperature, and the crystalline precipitate is filtered off under suction, washed with water and dried. 10.7 g (78% of theory) of 4-tert.-butyl-6-(4-chlorophenyl)-1-iodo-5-(1,2,4-triazol-1-yl)-hex-1-in-4-ol of melting point 155° C. are obtained.
