350 mg of palladium-on-charcoal at 10% are added to a solution containing 1.5 g (3.5 mmol) of methyl (E)-3-(2-benzyloxy-4-methoxyphenyl)-2-(tert-butoxycarbonyl-amino)acrylate in 15 ml of methanol. After stirring for hours under a hydrogen atmosphere, the reaction medium is filtered through celite and the filtrate is evaporated off. 850 mg of methyl 2-tert-butoxycarbonylamino-3-(2-hydroxy-4-methoxyphenyl)-propanoate are obtained in the form of a grey powder with a yield of 74%.
