Versuchsvorschrift
7.8 g (0.025 Mol) of benzyl 4-methoxycarbonylmethyloxyphenylacetate are exhaustively hydrogenated in 150 ml of methanol in the presence of 8 g of palladium hydroxide on charcoal at ambient temperature and under a hydrogen pressure of 50 psi. After the removal of the catalyst the mother liquor is evaporated to dryness under reduced pressure.
