실험 절차

3-(3,4-Dimethoxy-phenyl)-acrylic acid (compound of Example 2 (Step 1); 1.0 g, 4.8 mmol) was dissolved in methanol (10 mL) in the presence of catalytic amount of sulfuric acid. The reaction mixture was stirred at room temperature for 4 h. The reaction mixture was cooled at 5° C. and quenched with saturated sodium carbonate solution (2 mL). The solid obtained was filtered and dried.
