Procedure

230 mg of N1-(3-fluorobenzyl)-2-[1-[2-(2-oxo-1,2-dihydro-3-pyridinyl)ethyl]-2-piperidyl]acetamide obtained in Example 198, 0.08 ml of cyclopropylmethyl chloride, 450 mg of potassium carbonate and 5 ml of DMF were stirred at 60° C. for 1 hour. Water was added thereto, and the mixture was extracted with ethyl acetate. The extract was dried over sodium sulfate. The drying agent was filtered off, and the solvent was evaporated. The residue was purified by NH-silica gel column chromatography (hexane:ethyl acetate=1:1, subsequently ethyl acetate), to give 180 mg of a colorless oil.
