Procedure
In xylene (500 ml), D-tartaric acid (25.0 g, 0.17 mol) and benzylamine (19.6 g, 0.18 mmol) were heated under reflux for 18 hours by using a Dean-Stark water separator. After cooling, the reaction mixture was distilled under reduced pressure to remove the solvent, whereby 1-benzyl-(3S,4S)-dihydroxy-2,5-dioxopyrrolidine (33.7 g, 90%) was obtained as a brown solid.
