| Product | 2-(3-bromothiophen-2-yl)acetic acid | HCID 21260735 | — |
Reaction Steps
10% aqueous sodium hydroxide solution (100 ml) was added to this ester and stirring carried out for 14 hours at 50° C., after which ether extraction was carried out and unnecessary organic material eliminated. Next, acidification was performed with dilute hydrochloric acid and extraction carried out with dichloromethane. After drying, the solvent was distilled off and there was obtained 3-bromo-2-thiopheneacetic acid (4.7 g).
