실험 절차

To a solution of tert-butyl (3S,5R)-3-{(1H-benzimidazol-2-ylcarbonyl)(2-methylpropyl)amino}-5-(morpholin-4-ylcarbonyl)piperidine-1-carboxylate (308 mg), (2-chloroethoxy)ethene (192 mg) and potassium iodide (5 mg) in N,N-dimethylacetamide (5 ml) was added cesium carbonate (586 mg), and the mixture was stirred at 60° C. for 15 hr. The reaction mixture was cooled to room temperature, diluted with water, and extracted with ethyl acetate. The extract was washed with saturated brine, and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure. The residue was subjected to silica gel column chromatography, and a fraction eluted with ethyl acetate-hexane (6:4) was concentrated under reduced pressure to give the object product (323 mg).
