実験手順

To a stirred solution of (S)-tert-butyl 1-(2-(trimethylsilyl)ethoxycarbonylamino)-3-cyclohexylpropan-2-ylcarbamate (6.55 g, 15.4 mmol) in MeCN (100 mL) was added Et4NF (7.5 g, 50 mmol). The mixture was stirred overnight at rt and at 60° C. for 7 h. The mixture was concentrated and the oily residue was taken up in EtOAc (175 mL). The mixture was washed with water (2×50 mL) and brine (50 mL) and dried over Na2SO4. Removal of the solvent afforded (S)-tert-butyl 1-amino-3-cyclohexylpropan-2-ylcarbamate (3.39 g, 80%) as a syrup.
