Versuchsvorschrift

To a solution of 231 mg of tert-butyl {[3-(3-fluorophenyl)piperidin-4-yl]methyl}[(1R)-1-(1-naphthyl)ethyl]carbamate and 210 mg of methyl 3-chloro-4-{[(4-nitrophenoxy)carbonyl]amino}benzoate in 4.0 mL of THF was added 0.139 mL of triethylamine at room temperature, followed by stirring overnight. To the reaction mixture was added a saturated aqueous sodium hydrogen carbonate solution, followed by extraction with ethyl acetate. The organic layer was washed with water and saturated brine in this order, and dried over anhydrous sodium sulfate. After filtration, the filtrate was concentrated under reduced pressure to obtain 394 mg of a pale yellow foamy substance of methyl 4-({[4-({(tert-butoxycarbonyl)[(1R)-1-(1-naphthyl)ethyl]amino}methyl)-3-(3-fluorophenyl)piperidin-1-yl]carbonyl}amino)-3-chlorobenzoate as a crude product. ESI+: 674
