Reaction Steps
A mixture of 9.25 g (28 mmol) of ethyl γ-ketooctadecanoate and 9.00 g of ethylene glycol (145 mmol) was refluxed for 5 hours in 300 ml of toluene in the presence of a small amount of p-toluenesulfonic acid catalyst while removing water by means of Dean-Stark apparatus. The resulting mixture was washed with an aqueous saturated sodium bicarbonate solution and then with an aqueous saturated solution of sodium chloride. An oily product obtained by removing the solvent under reduced pressure was subjected to column chromatography over silica gel (eluent: ethyl acetate/hexane=1/10) to give 7.42 g (71% yield) of ethyl γ-ketooctadecanoate ethylene ketal.
