実験手順

The 4,5-diphenyl-2-thiophenecarboxylic acid (28 g, 0.1 mol) prepared as described above was heated to 220–230° C. until the evolution of carbon dioxide ceased. The residue was diluted in water and extracted with 100 mL of benzene. The organic phase was dried over MgSO4 and evaporated off to give the crystallized product. Yield 22.45 g (95%).
