실험 절차

To the sodium salt of 3-(3-sulfophenyl)acrylic acid methyl ester (2) (0.670 g, 2.53 mmol) benzene (2 mL), thionyl chloride (1.508 g, 0.9 mL, 12.67 mmol) and 3 drops of dimethylformamide were added and the resultant suspension was stirred at reflux for one hour. The reaction mixture was evaporated, the residue was dissolved in benzene (3 mL), filtered and the filtrate was evaporated to give the title compound (0.640 g, 97%).
