Abstract: A new synthetic method of 3-(2’-carboxyethyl)benzo [b]thiophene is developed, which can reduce side effects and achieved higher yields. The synthetic reaction of 3-chloromethyl benzo[b]thiopene took place under room tempera-ture. Homogeneous decarboxylation was carriedout under heat-
ing by using sodium methoxide instead of sodium hydride and
N,N-dimethylformamide (DMF) as a solvent. Meanwhile,the structure of 3-(2’-carboxyethyl)benzo[b]thiophene was confirmed by testing melt point, NMR, Mass Spectrometry and elementary analysis .

Key words: synthetic, molecular structure, analysis
