A solution of 20.0 g of methyl hexyl ketone in 100 ml of dioxane was dropped into a solution comprising 210 ml of diethyl carbonate, 12.8 g of sodium hydride dispersed in oil at a concentration of 60% by weight and 100 ml of dioxane in an argon atmosphere, and the mixture was refluxed overnight. Then, the solvent was removed and the residue was distilled under a reduced pressure to obtain 20.0 g of ethyl hexylketoacetate having a boiling point of 83° C. under 0.65 mmHg. The yield was 62.5%.
