الإجراء التجريبي

Dissolve (2R,5R)-5-[(1S,2S)-1-benzyloxy-2-dibenzylamino-3-(3,5-difluorophenyl)-propyl]-2-butyryloxymethyl-morpholine-4-carboxylic acid tert-butyl ester (295 mg, 0.397 mmol) in ethanol (29 mL). Add 20% palladium hydroxide on carbon (330 mg) and stir under 1 atmosphere of hydrogen gas for 48 hours. Filter through a filtering agent and wash with ethanol. Concentrate the filtrate to give the desired compound as a white foam (188 mg, 100%).
