Reaktionsschritte
6.8 g of potassium carbonate is added to a solution of 21.44 g of 3,4,5-trimethoxyphenylpropenoic acid and 45 ml of water then the medium is hydrogenated for one hour under a pressure of 1200-1300 mbars in the presence of 1.8 g activated charcoal with 10% palladium, in this way 2.1 l of hydrogen is absorbed. The reaction medium is filtered, followed by washing with water and acidifying with 50 ml of hydrochloric acid (2N). After separation, the residue is washed with water and dried under reduced pressure at ambient temperature. In this way 19.8 g of the expected product is obtained (M.P.=102-103° C.).
