실험 절차
In a flask equipped with a magnetic stirring bar and a rubber septum is dissolved the N-{(S)-1-hydroxy-3-phenyl-2-propyl}-5-benzyloxy-2-hydroxybenzamide in methanol. Nitrogen is bubbled through the solution and 10% Pd on charcoal is added. After flushing with nitrogen, the suspension is placed under hydrogen atmosphere and stirred for 2 hours. The suspension is flushed with nitrogen and filtered and rinsed over Celite. The filtrate is concentrated under vacuum. In this fashion is obtained N-{(S)-1-hydroxy-3-phenyl-2-propyl}-2,5-dihydroxybenzamide (85%).
