실험 절차

1-{1-[4-(5-Bromopentyloxy)benzoyl]-4-piperidinyl}-3,4-dihydrocarbostyril (2 g) and 4-trifluoroacetylaminopiperidine (2 g) are dissolved in dimethylformamide (40 ml), and thereto is added potassium carbonate (2 g) and the mixture is stirred overnight. The reaction mixture is poured into water, and the mixture is extracted with toluene/ethyl acetate (1:1), dried over magnesium sulfate, and purified by silica gel column chromatography (eluent; dichloromethane:methanol=50:1) to give 1-[1-{4-[5-(4-trifluoroacetylamino-1-piperidinyl)pentyloxy]benzoyl}-4-piperidinyl]-3,4-dihydrocarbostyril (2 g) as colorless oil.
