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 (Example 2) in 100 ml of acetic anhydride. The mixture was stirred at 70° C. for 4 hours. Thereafter, the reaction mixture was poured onto water and neutralised 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 pale yellow oil.
