実験手順

tert-Butyl (3S,5R)-3-{(1H-benzimidazol-2-ylcarbonyl)(2-methylpropyl)amino}-5-(morpholin-4-ylcarbonyl)piperidine-1-carboxylate (147 mg) was dissolved in dimethylformamide (12 ml), (2-bromoethyl)benzene (58 μl) and cesium carbonate (200 mg) were added and the mixture was stirred at 65° C. for 3 hr. (2-Bromoethyl)benzene (58 μl) was added, and the mixture was further stirred for 2 hr. The reaction mixture was concentrated under reduced pressure, diluted with water, and extracted with ethyl acetate. The extract was washed with saturated brine, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was subjected to silica gel chromatography, and a fraction eluted with ethyl acetate-hexane (1:9)-ethyl acetate was concentrated under reduced pressure to give the object product (164 mg).
