Conditions

Temperature
700 °C

Procedure

Tetrahydrofuran solvent (500 g), methacrylic 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 methacrylic acid are removed by using a rotary evaporator. The residue is distilled in vacuo to obtain pure 2-methyl-7-thiabicyclo[2.2.1]hept-5-ene-2-carboxylic acid of Chemical Formula 150 (yield: 50%).
