実験手順

2-(Trichloromethyl)-1H-benzimidazole (1.09 g) and tert-butyl (3R,5S)-3-(morpholin-4-ylcarbonyl)-5-(propylamino)piperidine-1-carboxylate (1.49 g) were dissolved in THF (120 ml), sodium hydrogen carbonate (3.52 g) and water (60 ml) were added and the mixture was stirred at room temperature for 2 hr. The reaction mixture was diluted with aqueous sodium bicarbonate, and extracted with ethyl acetate. The extract was washed with saturated brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure. The residue was subjected to basic silica gel column chromatography, and a fraction eluted with ethyl acetate-hexane (2:8-10:0) was concentrated under reduced pressure to give the object product (1.97 g).
