Reaktionsschritte
At 60° C. and a hydrogen pressure of 150 bar, 67.3 g of dimethyl (4-hydroxyphenyl)malonate in 500 ml of methanol were hydrogenated in the presence of 5 g of rhodium/carbon catalyst (5%). The catalyst was filtered off and the mixture was concentrated. This to give the title product as a colourless oil.
