Reaction Conditions

Reaction Steps

A mixture of 360 ml of acetyl chloride and 153 ml of acetic acid anhydride is added dropwise at 0° C., whilst stirring, to a solution of 576 g of crude 1-methyl-2-cyclohexyl-cyclohexanol in 750 ml of N,N-dimethylaniline. The mixture is then allowed to come to room temperature, after which is heated to 40° C. for 36 hours. Thereafter, the reaction mixture is poured onto ice and diluted with 1 liter of ether, and the organic phase is separated off and concentrated on a Rotavapor apparatus. The residue is then taken up in 2 liters of ether and the solution is washed with three times 200 ml of cold 2-N HCl and then with saturated bicarbonate solution and water until neutral, and is dried with anhydrous MgSO4 and evaporated in vacuo. 646 g of crude 1-acetoxy-1-methyl-2-cyclohexyl-cyclohexane are obtained.
