2,3-dichlorobenzoic acid

This paper provides a novel method for preparation of 2,3-dichlorobenzoic acid.

探索了一条合成抗癫痫药拉莫三嗪(Lamotrig-ine)的关键中间体2,3-二氯苯甲酸的新路线。

2,3-Dichlorobenzoic acid was prepared through diazotization and Meerwein reaction to give 2,3-dichlorobenzaldehyde from 2,3-dichloroaniline and followed by oxidation with potassium permanganate,and the overall yield was 45%.

笔者用2,3-二氯苯胺经重氮化、迈尔瓦音反应制得2,3-二氯苯甲醛,再经高锰酸钾氧化制得2,3-二氯苯甲酸,总收率45%。
