Procedure
Tetrahydrofuran solvent (500 g), acrylic acid (1.2 mole) and thiophene (1.0 mole) are introduced into a 2-liter flask. After stirring at 700° C. for 24 hours, the solvent and excessive acrylic acid are removed by using a rotary evaporator. The residue is distilled in vacuo to obtain pure 7-thiabicyclo[2.2.1]hept-5-ene-2-carboxylic acid of Chemical Formula 142 (yield: 80%).
