実験手順

(−)-3-Amino-8-(2-oxopyrrolidin-1-yl)-1-(thiophen-3-ylmethyl)-3,4-dihydroquinolin-2(1H)-one (500 mg) was dissolved in N,N-dimethylformaldehyde (5 mL), and to the solution were sequentially added N-tert-butoxycarbonyl-D-leucine monohydrate (382 mg), 1-hydroxybenzotriazole (207 mg), and 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (294 mg) under cooling on ice, followed by stirring at room temperature for one hour. The resultant mixture was extracted with ethyl acetate and water, and the organic layer was sequentially washed with saturated aqueous sodium bicarbonate solution and saturated aqueous sodium chloride solution, followed by drying over sodium sulfate. The solvent was evaporated under reduced pressure, and the thus-recovered residue was purified through silica gel column chromatography (chloroform:methanol=50:1), whereby the title compound (832 mg) was yielded.
