Versuchsvorschrift
10% Pd/C (150 mg) was added to a solution of (S)-2-(tert-butoxycarbonylamino)-3-(2-nitro-6-(trifluoromethyl)phenoxy)propanoic acid (1.5 g, 3.8 mmol) in MeOH and the mixture stirred under H2. After 4 h the mixture was filtered through Celite, the filter cake washed with MeOH and the filtrate concentrated to afford (S)-3-(2-amino-6-(trifluoromethyl)phenoxy)-2-(tert-butoxycarbonylamino)propanoic acid (1.23 g, 89%) which was used without purification.
