A convenient route for preparing 1,4,8-trimethoxy-2-naphthalenecarbaldehyde was accomplished by the following: The starting material, 4,8-dimethoxy-1-naphthol, was prepared from 1,5-dimethoxynaphthalene through 1-bromo-4,8-dimethoxynaphthalene. Formylation of this naphthol and subsequent methylation gave 1,4,8-trimethoxy-2-naphthalenecarbaldehyde.
一种方便制备1,4,8-
三甲氧基-
2-萘甲醛的途径如下:起始原料4,8-二甲氧基-1-
萘醇是通过
1,5-二甲氧基萘经过
1-溴-4,8-二甲氧基萘制备的。对该
萘醇进行甲酰化反应后,再进行甲基化反应,最终得到1,4,8-
三甲氧基-
2-萘甲醛。
