Versuchsvorschrift
To a solution of 3-[3,4-Bis-(2-methoxy-ethoxy)-phenyl]-acrylic acid (20 g, 67.5 mmol) in EtOAc (100 ml) and MeOH (100 ml) was added carefully 10% Pd/C (1.5 g), then the mixture was shaken in Parr apparatus for 5 hs under 30-40 psi of hydrogen. The solution was passed through a celite pad, and the filtrate was concentrated to give product (15 g, 78.5%). LC-MS: m/e 297 (M−1)
Aufarbeitung
