Reaction Steps

To a solution of (5-bromo-benzofuran-2-yl)-methanol (1.6 g, 3.7 mmol) and 4-tert-butylstannanyl-pyridazine (1 g; 4.4 mmol) in 15 mL dry toluene, was added tetrakis(triphenylphosphine)palladium (0) (130 mg). The mixture was stirred at 95° C. overnight. After allowing the mixture to come to room temperature, the solution was poured into water, extracted, dried over MgSO4, and filtrated to afford 2.4 g of crude product that was further purified by chromatography to afford (5-pyridazin-4-yl-benzofuran-2-yl)-methanol.
