Procedure
cis-2-Butyl-4-oxocyclohexane carboxylic acid ethyl ester (9.0 g; 40 mmole), ethylene glycol (2.73 g; 44 mmole) and p-toluenesulphonic acid (100 mg) were refluxed in benzene 80 ml) using a Dean-Stark water trap. After 12 hours the mixture was cooled, diluted with diethyl ether and washed with saturated aqueous sodium bicarbonate followed by water. Drying over MgSO4 and evaporation gave a liquid (10.80 g; 100%) which was pure enough to use directly. Found: C, 66.71; H, 9.79. C15H26O4 requires C, 66.64; H, 9.69%.
