Abstract:2,3-Dichlorobenzoic acid is the key intermediate for antiepileptic drug lamotrigine and the other medicine for the treatment of central nervous system (CNS)disorders and disease. 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%. In addition,each operation of the reactions and purification was also studied .
Key words:2; 3-dichlorobenzoic acid; 3-dichlorobenzaldehyde; antiepileptic; lamotigine; intermediate; synthesis
