报道了5-硝基愈创木酚钠(5-NGS)的合成方法。由愈创木酚与乙酐在100℃回流1 h 得到乙酰化产物。反应中生成的乙酸不必分离,再补加一定量乙酸作为下一步反应的溶剂。用发烟硝酸直接硝化上述乙酰化物,总收率高于70% 。用IR、1HNMR和MS对产物的结构进行了表征
The synthesis of 5-nitro guaiacol sodium (5-NGS) has been reported. Acetylated product was obtained by refluxing guaiacol with acetic anhydride at 100 ° C for 1 h. Acetic acid generated in the reaction does not have to be separated, and then a certain amount of acetic acid is added as a solvent for the next reaction. With fuming nitric acid direct nitrification acetylation, the total yield higher than 70%. The structure of the product was characterized by IR, 1HNMR and MS
