Sodium Carbonate → 3-Bromo-6-(2-fluoro-phenyl)-pyridazine

Participants

Reaction Steps

300 mg (1.26 mmol) of 3,6-dibromopyridazine, 176.5 mg (1.26 mmol) 2-fluoro-phenylboronic acid, 34.7 mg (0.038 mmol) of tetrakis(triphenylphosphine)palladium and 1.26 ml of an aqueous 1 M sodium carbonate solution in 15 ml of DME were heated under reflux for 3 h. After cooling, the reaction mixture was poured onto water and extracted with ethyl acetate. The combined organic phases were dried, evaporated, and the product purified by RP18 chromatography. Yield: 62 mg.
