100% | at 50℃; for 18 h; | To a solution of methyl 5-chlorothiophene-2-carboxylate (10.0 g, 61.5 mmol) in dry MeOH (55 mL) was added H2SO4 (5-7 mL). The reaction mixture was heated to 50° C. for 18 h and was then concentrated under vacuum. The residue was dissolved in DCM and washed several times with saturated NaHCO3 solution. The organic fraction was dried (Na2SO4), concentrated under vacuum provide 4-chlorothiophene-2-carboxylic acid, which was and used directly without further purification 10.85 g (˜100percent). 1H NMR (400 MHz, DMSO-d): δ 7.66 (d, 1H, J=4.0 Hz), 7.23 (d, 1H, J=4.4 Hz), 3.81 (s, 3H). |
