3-Hydroxyacetophenone → 1-[3-(3-Phenylpropoxy)phenyl]ethan-1-one

참여 물질

반응 단계

3′-Hydroxyacetophenone (6.81 g, 50 mmol) and 1-bromo-3-phenyl propane (11.95 g, 60 mmol) were dissolved in dimethylformamide (70 ml). Then, potassium carbonate (15 g) and sodium iodide (0.5 g) were added thereto and the mixture was allowed to react for 7 hours at 80° C. Ethyl acetate (300 ml) and purified water (200 ml) were further added to the reaction mixture prior to stirring for 30 min. The organic layer extracted with ethyl acetate was dried over anhydrous magnesium sulfate, concentrated, and the resulting residue was purified by silica gel column chromatography (ethyl acetate:hexane=1:5) to obtain the title compound (12.0 g, yield 94.2%) as a gel.
