Reaction Conditions

Reaction Steps

A mixture of 1-[2-(3,3,5,5-tetramethylcyclohexyl)phenyl]piperazine (120 mg, 0.399 mmol) produced in Example (8b), 1,2-epoxyhexane (240 mg, 2.39 mmol) and 2-propanol (0.8 mL) was stirred for 18 hours at an external temperature of 80° C. The reaction mixture was concentrated under reduced pressure to give a residue, which was purified by NH silica gel column chromatography (ethyl acetate/heptane) to give 116 mg of 1-{4-[2-(3,3,5,5-tetramethylcyclohexyl)phenyl]piperazin-1-yl}hexan-2-ol as a light yellow solid. This compound (12 mg, 0.030 mmol) was dissolved in diethyl ether and a 4N solution of hydrogen chloride in ethyl acetate (0.0083 mL, 0.033 mmol) was added. The mixed solution was concentrated under reduced pressure and the obtained solid residue was washed with a diethyl ether-heptane mixed solvent and then dried under reduced pressure to give 10 mg of the title compound as a colorless solid.
