Procedure

(E)-3-(4′-Propyl-bicyclohexyl-4-yl)acrylic acid ethyl ester is hydrogenated in THF in the presence of palladium on charcoal. After 1 eq. of hydrogen has been consumed the catalyst is filtered off, the solvent is evaporated and the residue is filtered through silica yielding 3-(4′-propyl-bicyclohexyl-4-yl)-propionic acid ethyl ester as a colourless oil.

Workup

  1. filtrationis filtered off
  2. customthe solvent is evaporated
  3. filtrationthe residue is filtered through silica
