반응 단계

6.8 g of potassium carbonate were added to a solution of 21.44 g of 3,4,5-trimethoxyphenylpropenoic acid and 45 ml of water and the mixture was hydrogenated for one hour under a pressure of 1200-1300 mbar in the presence of 1.8 g of activated charcoal with 10% of palladium during which 2.1 liters of hydrogen were absorbed. Filtration was carried out, followed by washing with water and acidifying with 50 ml of hydrochloric acid (2N). The product was separated off, washed with water and dried under reduced pressure at ambient temperature to obtain 19.8 g of the expected product melting at 102-103° C.
