Reaktionsschritte

A mixture of the 1-[2-(3,3,5,5-tetramethylcyclohexyl)phenyl]piperazine (100 mg, 0.333 mmol) produced in Example (8b), 2-chloroethyl methyl sulfide (38.7 mg, 0.349 mmol), potassium carbonate (78.2 mg, 0.566 mmol) and acetonitrile (2 mL) was stirred for 8 hours and 30 minutes at an external temperature of 80° C. The reaction mixture was concentrated and the resultant residue was purified by NH silica gel column chromatography (ethyl acetate/heptane) to give 88 mg of 1-(2-methylsulfanylethyl)-4-[2-(3,3,5,5-tetramethylcyclohexyl)phenyl]piperazine as a colorless solid.
