Acetyl chloride → HCID 21320009, compound

Participants

Reaction Steps

8.0 g (0.1 mol) of acetyl chloride are added to 20.6 g (0.1 mol) of 1-imidazol-1-yl-1-phenoxy-3,3-dimethyl-butan-2-ol in 100 ml of ethyl acetate at room temperature. The mixture is then heated under reflux for 4 hours. It is allowed to cool and concentrated by distilling off the solvent in vacuo. The residue is taken up in benzene and the solution is washed with aqueous sodium bicarbonate solution and dried over sodium sulphate. The solvent is distilled off under a water pump vacuum and the residue is recrystallized from petroleum ether. 20.6 g (45% of theory) of 2-acetoxy-1-phenoxy-1-imidazol-1-yl-3,3-dimethyl-butane are obtained as a mixture of isomers with a melting point of 114°-121° C.
