실험 절차

(1R*,2R*)-4-Benzyloxymethyl-N1-[(5-chloroindol-2-yl)carbonyl]-1,2-cyclopentanediamine (794 mg) was dissolved in N,N-dimethylformamide (150 ml), and lithium 5-methyl-4,5,6,7-tetrahydrothiazolo[5,4-c]pyridine-2-carboxylate (694 mg), 1-hydroxybenzotriazole monohydrate (61 mg) and 1-(3-dimethylaminopropyl)-3-ethyl-carbodiimide hydrochloride (1.15 g) were added to stir the mixture overnight at room temperature. The reaction mixture was concentrated under reduced pressure, and water was added to the residue to conduct extraction with dichloromethane. The resultant organic layer was dried over anhydrous sodium sulfate. The solvent was distilled off under reduced pressure, and the residue was purified by preparative thin-layer chromatography (dichloromethane:acetone=2:1) to obtain Stereoisomer A (378 mg) and Stereoisomer B (354 mg) of (1R*,2R*)-4-benzyloxymethyl-N1-[(5-chloroindol-2-yl)carbonyl]-N2-[(5-methyl-4,5,6,7-tetrahydrothiazolo[5,4-c]pyridin-2-yl)carbonyl]-1,2-cyclopentanediamine.
