摘要
本文介绍了在三氯化磷存在下,水杨酸与愈创木酚作用生成水杨酸愈创木酚酯的方法,产物用异丙醇重结晶,收率为75.4%.所得产物再用吡啶作催化剂进行乙酰化,得到呱西替柳,收率为96~97%.
A improvement of synthetic method of which guaiacol salicylate was pro-duced by using salicylic acid and guaiacol as starting material under the condition of phosphorus trichlororide was suggested in this paper. The obtained ratio of the prod-ucts recrystalled from isopropanol is about 75.4%. The products derived from the last preparation was acetylated by using pyridine as a catalyst, guacetisal was obtained finally. The obtained ratio of guacetisal is 96-97%.
