Reaction Conditions

Reaction Steps

Lithium aluminum hydride (0.24 g) was added to diethyl ether (15 mL), to which was then added dropwise ethyl 4,4-difluorocyclohexanecarboxylate (1.0 g) in diethyl ether (2 mL), and the reaction was stirred at reflux under nitrogen for 4 hours. The reaction was cooled to 0° C., followed by the careful addition of water (0.24 mL), 4N aqueous NaOH (0.24 mL), and additional water (0.72 mL). Then Na2SO4 and diethyl ether (40 mL) were added and the mixture was stirred for 30 minutes. After filtration through diatomaceous earth and concentration, the title compound was used in the next step without further purification.
