Reaction Steps

A mixture of 1-[4-(4-methoxypiperidin-1-yl)-2-spiro[5.5]undec-2-en-3-yl-phenyl]piperazine (20 mg, 0.0472 mmol) produced in Example (39e), 2-bromoethyl methyl ether (0.0049 mL, 0.0519 mmol), potassium carbonate (11.1 mg, 0.0803 mmol) and acetonitrile (1 mL) was stirred for 5 hours at an external temperature of 80° C. Ethyl acetate and brine were added to the reaction mixture and extraction was performed three times with ethyl acetate. The separated organic layers were concentrated. The resultant residue was purified by NH silica gel column chromatography (ethyl acetate/hexane) to give 1-(2-methoxyethyl)-4-[4-(4-methoxypiperidin-1-yl)-2-spiro[5.5]undec-2-en-3-ylphenyl]piperazine.
