摘要:
The invention concerns a method for preparing 2-thienyl-2-ethanol which consists in: (a) metallation of thiophene using an alkali metal in the presence of an electron-transferring agent; (b) treating the resulting compound with ethylene oxide; (c) hydrolyzing the resulting thienyl derivative, thereby obtaining the desired compound. 2-thienyl-2-ethanol is a synthesis intermediate.
