Reaction Steps
This material was re-benzylated as follows: 4-[2-(2,4-Dichloro-phenyl)-propionyl]-1H-pyridin-2-one (100 mg) was dissolved in absolute benzene (6 mL) and silver carbonate (65 mg) and benzyl bromide (70 mg, 0.05 mL) were added. The mixture was stirred at 50° C. over night and was then poured into ice water. The aqueous phase was extracted with ethyl acetate and the organic layer was washed with brine, dried over Na2SO4 and evaporated. The residue was purified by flash chromatography (20 g silica gel, gradient of ethyl aceate in heptane (0 to 20%)) to give 1-(2-benzyloxy-pyridin-4-yl)-2-(2,4-dichloro-phenyl)-propan-1-one (78 mg) as a colorless oil. MS (m/e)=386.0 [MH+].
