Participants

Reaction Steps

14 g (0.04 mol) of 4-((4-chlorophenoxy)-(1H-1,2,4-triazol-1-yl)-methyl)-5,5-dimethyl-hex-1-yn-4-ol (obtained as described in Example 1), dissolved in 75 ml of dioxane, were added dropwise to a solution of 7.7 g (0.048 mol) of bromine in 40 ml of 10% strength sodium hydroxide solution at 0° C. After five hours, the reaction mixture was stirred into ice water. The precipitated product was filtered off under suction, washed with water and dried. 14.2 g (86.1% of theory) of 1-bromo-4-((4-chlorophenoxy)-(1H-1,2,4-triazol-1-yl)-methyl)-5,5-dimethyl-hex-1-yn-4-ol of melting point 156° to 160° C. were obtained.
