Procedure

Lithium aluminum hydride (1.90 g) was added to a recovery flask, and THF (300 mL) was added thereto in an ice bath. A solution of ethyl 2-(2-fluorophenyl)cyclohex-1-enecarboxylate obtained in Preparation Example 1-(2) (10.3 g) in THF (100 mL) was added dropwise to the reaction solution at the same temperature, and the mixture was stirred for one hour. Water (1.90 mL), a 5 N sodium hydroxide solution (1.90 mL) and water (5.70 mL) were sequentially added to the reaction solution. Anhydrous magnesium sulfate was further added, followed by extraction with ethyl acetate. The insoluble matter was separated by filtration and the filtrate was concentrated under reduced pressure to obtain the title compound (8.88 g).
