Procedure

(R)-3-(N-biphenyl-4-ylmethyl-N′-t-butoxycarbonylhydrazino)-2-hydroxypropionic acid methyl ester (300 mg, 749 μmol, 1.0 eq.) was dissolved in DCM (3.0 mL). TFA (3.0 mL) was added and the mixture was stirred at room temperature until the reaction was complete (approximately 1 hour). The mixture was concentrated to yield the title compound, which was used without further purification.
