実験手順

2.00 Grams of 6-(4-carboxybutoxy)carbostyril is suspended in 60 ml of chloroform. Thereto is added 1.40 g of DBu. The mixture is stirred for 30 minutes at room temperature. 1.05 g of isobutyl chloroformate is added with ice cooling. Then, there is dropwise added at room temperature 1.61 g of N-(cyclohexylmethyl)-N-[2-(1-pyrrolidinyl)ethyl]amine. The mixture is stirred for 3 hours at room temperature. Then, a 0.5N aqueous sodium hydroxide solution is added, and the mixture is stirred for 10 minutes. Extraction with chloroform is effected. The extract is washed with water and dried with anhydrous magnesium sulfate. The solvent is removed by evaporation. The resulting residue is purified by a silica gel column chromatography (chloroform:methanol=20:1) and recrystallized from diethyl ether to obtain 1.00 g of 6-[4-{N-cyclohexylmethyl-N-[2-(1-pyrrolidinyl)ethyl]aminocarbonyl}butoxy]carbostyril.
