Versuchsvorschrift
2-amino-4-(trifluoromethyl)benzoic acid (0.32 g) and tert-butyl 3-[(2-methylpropyl)amino]piperidine-1-carboxylate (0.4 g) were dissolved in 1,2-dichloroethane (20 ml), diethyl phosphorocyanidate (0.31 g) was added and the mixture was stirred at 70° C. overnight. The reaction mixture was poured into water, and the mixture was extracted with ethyl acetate. The extract was washed with saturated brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure, and the residue was subjected to silica gel column chromatography, and the fraction eluted with ethyl acetate-hexane (0:10-1:1) was concentrated under reduced pressure to give the object compound (0.33 g).
