Versuchsvorschrift

(3R,5S)-5-{[(Benzyloxy)carbonyl]amino}-1-(tert-butoxycarbonyl)piperidine-3-carboxylic acid (49.2 g), morpholine (11.4 ml), 1H-benzotriazol-1-ol (10.0 g) and triethylamine (40 ml) were dissolved in DMF (250 ml), WSC.HCl (30.0 g) was added, and the mixture was stirred at room temperature for 4 days. The reaction mixture was poured into water, and the mixture was extracted with ethyl acetate. The extract was washed successively with saturated aqueous sodium hydrogen carbonate solution and saturated brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure to give the object product (62.9 g).
