실험 절차
L-Tartaric acid (90 g, 600 mmol) and benzylamine (64.3 g, 600 mmol) were mixed in 400 mL of o-xylene and the mixture was refluxed 14 hours with a Dean-Stark trap. The pellet was filtered off and the compound was crystallized from hot EtOH (1600 mL). The formed crystals were washed with cold hexane to afford the title compound.
