실험 절차
2.10 g (6.0 mmol) triacetoxystilbene were dissolved under reflux in 19.3 ml methanol and 39 ml ammonium acetate solution (25%) was added to the solution. The reaction mixture was stirred for three hours at the same temperature and afterwards the methanol was distilled off. By cooling to 5° C. the product crystallized and could be filtered off. 1.33 g (5.82 mmol, 97%) resveratrol were obtained as a pure compound. The mother liquor was purified by extraction with methyl-butyl-ether and neutralized with ammonia. After concentration under reduced pressure the solution was used again for the described reaction.
