Procedure

A mixture of the 1-[2-(4-t-butylcyclohexyl)phenyl]piperazine (30 mg, 0.0998 mmol) produced in Example (10a) and chloroform (0.5 mL) was cooled in an ice bath and stirred. Methyl vinyl ketone (0.017 mL, 0.200 mmol) was added to the mixture, followed by stirring for 2 hours under the same conditions. The reaction mixture was purified by NH silica gel column chromatography (ethyl acetate/hexane) to give 30 mg of the title compound as a colorless oil, as a mixture of diastereomers at the position of t-butylcyclohexyl.
