Versuchsvorschrift

To a solution of 1-phenylcyclohexanecarboxylic acid (1.32 g) in tetrahydrofuran (30 mL) at 0° C. was slowly added 2 M LiAlH4 in tetrahydrofuran (6.46 mL). The resulting mixture was stirred at room temperature overnight and cooled to 0° C. Ice water was added to quench the reaction. The resulting mixture was diluted with ethyl acetate and washed with 1 N aqueous NaOH and water. The organic layer was dried over Na2SO4, filtered, and concentrated to provide the title compound.
