Versuchsvorschrift
A solution of (R)-3-[N-(4-bromobenzyl)-N′-t-butoxycarbonylhydrazino]-2-hydroxypropionic acid methyl ester (25 g, 62 mmol) in EtOH/HCl (1M, 310 mL, 0.3 mol) was stirred overnight until the reaction was complete. The mixture was then concentrated and the residue was washed with EtOAc (120 mL) and filtered. The solids were collected to yield the title compound as a white solid HCl salt (15 g).
