Procedure

A solution of (S)-methyl 2-(benzyloxycarbonylamino)-5-cyclopropyl-4,4-difluoropentanoate (570 mg, 1.87 mmol) in dioxane/4N-HCl (9 mL, 37 mmol) was stirred at RT for two hr, after which the solvent was removed by rotoevaporation to give 450 mg of (S)-methyl 2-amino-5-cyclopropyl-4,4-difluoropentanoate hydrochloride as a beige solid.
