Versuchsvorschrift
The ethyl 2-(2-(tert-butoxycarbonylamino)-3-phenylpropanoyloxy)benzoate (1.2 g, 2.9 mmol) was dissolved in CH2Cl2 (10 mL) and TFA (4 mL). The reaction was stirred (RT, 3 h) and then concentrated. The crude material was purified by silica chromatography (0-10% MeOH/CH2Cl2) to afford 0.63 g of ethyl 2-(2-amino-3-phenylpropanoyloxy)benzoate. Mass calculated for C18H19NO4=313.35. found: [M+H]+=314.1
