YieldReaction ConditionsOperation in experiment
63% A suspension of thiophene-3-yl acetic acid (2.22 g, 15.6 mmol) and N-bromosuccinimide (2.78 g, 15.6 mmol) in DCM (140 mL) was kept in an ultrasound bath for 30 minutes. The solvent was evaporated under reduced pressure, and methanol (140 mL) and conc. sulfuric acid (0.5 mL) were added. The solution was stirred at 70 C for 16 hours. After cooling to room temperature, the solution was neutralized by the addition of saturated aqueous Na2CO3 (saturated), extracted with DCM (3 × 80 mL), and the combined organic solutions were dried over Na2SO4. After evaporation of the solvent, the crude product was purified by column chromatography (ca. 300 g SiO2, hexane/EA 1:0 9:1) to give 10 (2.30 g, 15.6 mmol, 63%) as colorless oil.
