반응 단계

Into a 100 mL single neck flask were placed 1,4-dibromo-2-fluorobenzene (2.35 g, 9.2 mmol), dichlorobis(triphenylphosphine) palladium (II) (0.645 g, 0.92 mmol), tributyt (1-ethoxyvinyl)tin (10 g, 27.7 mmol), in THF (50 mL), and the mixture was heated at reflux while stirring for 18 hours. The reaction was cooled to room temperature and poured into 5N HCl (20 mL). The product was extracted with EtOAc and the organic layer was separated and washed twice with water, dried over anhydrous Na2SO4, filtered, and concentrated under reduced vacuum. The resulting semi-solid was purified via flash chromatography (Silica gel, isocratic) and eluting with a solvent of Hexanes/EtOAc 90:10 to provide the intermediate title compound, 1-(4-acetyl-2-fluorophenyl)ethan-1-one, (1.65 g, 100%) as a solid. Electron spray M.S. 180.9 (M*)
