Procedure

To a solution of 4-phenylcyclohexanone oxime (0.310 g, 1.64 mmol) in THF (3 ml) was added 1M lithium aluminum hydride in THF (3.44 ml, 3.44 mmol), and the reaction was heated to reflux for 4 hours. The reaction was allowed to cool to ambient temperature, and water (0.131 ml), 1M NaOH (0.131 ml) and additional water (0.393 ml) were added, and the reaction was stirred for 30 minutes. The reaction was diluted with EtOAc and filtered. The filtrate was concentrated to yield 100 mg of the title compound (34.8% yield) as a 1:1 mixture of cis and trans isomers.
