Reaction Steps

3-[4-(3-Hydroxy-prop-1-ynyl)-phenyl]-1-(2-methyl-pyridin-4-yl)-3-o-tolyl-propan-1-one (example 85, step 1; 40 mg) in ethyl acetate (6 mL) was hydrogenated in the presence of Pd (5% on carbon, 7 mg) at room temperature for 1.5 hours. The solution was filtered over decalite, the filter residue was washed with ethyl acetate, and the solution was evaporated to yield 3-[4-(3-hydroxy-propyl)-phenyl]-1-(2-methyl-pyridin-4-yl)-3-o-tolyl-propan-1-one (41 mg, 64%) as a colorless oil, which was directly subjected to the next step.
