Versuchsvorschrift

0.5 mol of Compound A were stirred at 40° C. and under 20 bar of H2 in 3,000 ml of ethyl acetate with the addition of 27 g of palladium/carbon (5% Pd) and 1 mol of triethylamine; during the course of the reaction a further 15 g of Pd/C were added in total. After distillation, 84% of Compound B was obtained.
