Reaction Steps

Dissolve (2S,5R)-5-[(1S,2S)-2-Acetylamino-1-benzyloxy-3-(3,5-difluorophenyl)-propyl]-2-(3-cyclopentylpropoxy)-morpholine-4-carboxylic acid tert-butyl ester (67 mg, 0.106 mmol) in neat trifluoroacetic acid under nitrogen. After 20 min, dilute the reaction mixture with dichloromethane and concentrate it on the rotary evaporator four times, then dilute with benzene and concentrate again. Dry the residue under vacuum to give the title compound.
