Procedure

(±)-(E)-N-[4-[1-(1H-imidazol-1-yl)-2-methylpropyl]phenyl]-2-methyl-3-phenyl-2-propenamide (0.0144 mol) in methanol (200 ml) was hydrogenated with palladium-on-charcoal 10% (0.52 g) as a catalyst at RT over a 5 hour period under a 1 bar pressure in a Parr apparatus. After uptake of hydrogen, the catalyst was filtered through celite and the solvent was evaporated. The residue was crystallized from 2-butanone/DIPE, yielding 4.9 g (94%)of (±)-N-[4-[1-(1H-imidazol-1-yl)-2-methylpropyl]phenyl]-α-methyl-benzenepropanamide (compound 164).
