Reaction Steps

0.68 g (17.0 mmol) of sodium hydride (60% oily) was suspended in 7 ml of THF. 1.36 g (10.6 mmol) of 2-cyclohexylethanol was added to the obtained suspension at 0° C., and they were stirred at 40° C. for 30 minutes. 2.00 g (8.82 mmol) of benzyl 4-chloroacetoacetate was added to the obtained mixture at room temperature, and they were refluxed at 100° C. for 3 hours. 1 N hydrochloric acid was added to the reaction mixture. After the extraction with ethyl acetate, the organic layer was washed with 10% aqueous sodium hydroxide solution and saturated aqueous sodium chloride solution, dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The residue was purified by the silica gel chromatography (hexane/ethyl acetate=4/1) to obtain the title compound.
