実験手順

To a mixture of the product of Step B (330 mg) and N,N-diisopropylethylamine (0.28 mL) in dichloromethane (3 mL) and N,N-dimethylformamide(1 mL), was added 1-piperidinepropionic acid (256 mg), WSC.HCl (1-Ethyl-3-(3′dimethylaminopropyl)-carbodiimide.HCl) (312 mg), and 1-hydroxybenzotriazole hydrate (220 mg). The solution was stirred at ambient temperature for approximately 18 hours. The mixture was poured into a separatory funnel and washed sequentially with an equal volume of 1 N sodium hydroxide and water. The organic phase was dried over sodium sulfate, decanted and evaporated. The residue was purified via silica gel chromatography (methanol/dichloromethane) to yield the title compound (128 mg).
