Versuchsvorschrift

A mixture of 1-[3,5-bis(trifluoromethyl)benzoyl]-2-[3-[(2-methoxyethoxy)methoxy]-4-methylbenzyl]piperazine (0.4 g), 1-chloro-3-(3-pyridyl)-2-propyne hydrochloride (0.17 g), potassium carbonate (0.52 g) and a trace of potassium iodide in N,N-dimethylformamide (7 ml) was stirred for 4 hours at 80° C. After cooling, the solvent was removed by evaporation, and ethyl acetate and aqueous sodium hydrogen carbonate solution were added thereto. The organic layer was separated, dried over magnesium sulfate, and evaporated under reduced pressure. The residue was purified by column chromatography on silica gel using ethyl acetate. The fractions containing the objective compound were collected and evaporated under reduced pressure to give 1-[3,5-bis(trifluoromethyl)benzoyl]-2-[3-[(2-methoxyethoxy)methoxy]-4-methylbenzyl]-4-[3-(3-pyridyl)-2-propynyl]piperazine (0.44 g) as an oil.
