Procedure

To a mixture of 4-[3-piperazin-1-yl-4-(3,3,5,5-tetramethylcyclohexyl)phenyl]morpholine (14 mg, 0.0363 mmol) produced in Example (81e), butyraldehyde (0.0097 mL, 0.109 mmol) and tetrahydrofuran (0.5 mL) was added sodium triacetoxyborohydride (23 mg, 0.109 mmol), followed by stirring for 1 hour and 30 minutes at room temperature. Saturated aqueous solution of sodium hydrogencarbonate was added to the reaction mixture and extraction was performed with ethyl acetate. The solvent was distilled of by nitrogen stream to the separated organic layer. The resultant residue was purified by NH silica gel column chromatography (ethyl acetate/heptane) to give 4-[3-(4-butylpiperazine-1-yl)-4-(3,3,5,5-tetramethylcyclohexyl)phenyl]morpholine.
