الإجراء التجريبي

A solution of 2.9 g of cis-cyclohexane-1,4-dicarboxylic acid in 25 ml of acetic anhydride was heated under reflux for 2.5 hours. The solvent was removed by evaporation in vacuo, and the residue was triturated under diethyl ether several times. The residue was dried under high vacuum to give 2.5 g (97% yield) of the title compound.
