Reaction Steps

Boc-(S)-3-amino-2-benzylpropionic acid (105 mg, 0.38 mmol, PepTech) was dissolved in TFA (4 mL) and CH2Cl2 (4 mL). The resulting mixture was stirred at room temperature for 3 hours. The volatiles were removed in vacuo and the residue was dissolved again in CH2Cl2 (4 mL). The volatiles were removed again in vacuo to give the title compound as its TFA salt, which was used in the subsequent step without further purification.
