Reaction Conditions

Reaction Steps

2 ml of pyridine were added to a solution of 13.15 g (0.05 mol) of 1-cyclohexyl-4,4-dimethyl-2-(1,2,4-triazol-1-yl)-pent-1-en-3-ol (prepared as described in Example II-2) in 100 ml of acetic anhydride. The mixture was stirred for four hours at 70° C. The reaction mixture was thereafter poured onto water and was neutralized with sodium bicarbonate. The aqueous phase was extracted several times with ether. The combined ether phases were dried over sodium sulphate and concentrated. 11.2 g (70.8% of theory) of 3-acetoxy-1-cyclohexyl-4,4-dimethyl-2-(1,2,4-triazol-1-yl)-pent-1-ene were obtained as a slightly yellow oil.
