Reaction Steps

The hydrogenation of (E)-5-[2-(1,2,3,4-tetrahydro-9-octyl-9H-dibenzo[b,d]pyrrol-6-yl)ethenyl]-2-furancarboxylic acid methyl ester from Example 33 was carried out at normal pressure and at room temperature. Thus 5.3 g of this material dissolved in 55 ml of absolute ethyl alcohol was hydrogenated in the presence of 0.3 g of 10% Palladium on carbon to give 4.0 g (76.0%) of 5-[2-(1,2,3,4tetrahydro-9-octyl-9H-dibenzo[b,d]pyrrol-6yl)ethyl]-2-furancarboxylic acid methyl ester as a yellow oil after chromatographic purification.
