Reaction Steps
Ethyl 3-bromo-4-mercaptobenzenecarboximidate (3.00 g) was dissolved in ethanol (100 ml), and water (10 ml) and then concentrated sulfuric acid (10 ml) were added dropwise thereto at 0° C. and stirred overnight at room temperature. Zinc (1 g) was added to the reaction system and the resulting mixture was stirred at room temperature for 2 hours to induce the production of a monomer. After the zinc powder was removed by filtration through Celite, the ethanol was distilled off under reduced pressure, followed by extraction with ethyl acetate, and the organic layer was washed with water (×4). The organic layer was dried over anhydrous sodium sulfate and then concentrated to obtain ethyl 3-bromo-4-mercaptobenzoate (2.58 g) as a light-yellow solid.
