Versuchsvorschrift

Subsequently, 2-(3-chloromethyl-benzoylamino)-5-(2-oxo-pyrrolidin-1-yl)benzoic acid methyl ester (14 mg) was dissolved in anhydrous methylene chloride (5 ml). Triethylamine (7 mg: dissolved in 2 ml of anhydrous methylene chloride) and diisopropanolamine (compound B′) (10 mg: dissolved in 2 ml of anhydrous methylene chloride) were added dropwise to the solution at 0° C., and the mixture was stirred at room temperature for 24 hr. After the completion of the reaction, distilled water was added thereto at room temperature, and the mixture was subjected to separatory extraction with chloroform. The organic layer was washed with saturated brine, was dried over sodium sulfate, and was then concentrated under the reduced pressure. The residue was purified by column chromatography eluted with a chloroform-methanol system to give 2-(3-{[bis-(2-hydroxy-propyl)-amino]-methyl}-benzoylamino)-5-(2-oxo-pyrrolidin-1-yl)-benzoic acid methyl ester (8.0 mg, yield 47%).
