Versuchsvorschrift

To a solution of 5,6-difluoro-2-(trichloromethyl)-1H-benzimidazole (500 mg) and tert-butyl (3S,5R)-3-[(2-methylpropyl)amino]-5-(morpholin-4-ylcarbonyl)piperidine-1-carboxylate (680 mg) in THF (50 ml) were added sodium hydrogen carbonate (1.3 g) and water (20 ml), and the mixture was stirred at room temperature for 1 hr 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 (1:1-1:0) was concentrated under reduced pressure to give the object product (710 mg).
