참여 물질

반응 단계

3-thiophenecarboxylic acid (2.0 g) was dissolved in MeOH (27 mL) and concentrated sulphuric acid (1.5 mL) was added. The reaction mixture was refluxed for 3 hours and 30 min., then concentrated under reduced pressure. A saturated NaHCO3 solution was added and the mixture was extracted with ethyl acetate. The organic phase was dried over Na2SO4 and concentrated in vacuo to give 1.98 g of the title compound as a colourless liquid which was used without further purification.
