Reaction Steps

To a solution of 4-bromopyridazine (131 mg, 0.824 mmol) in 1,2-dimethoxyethane (16.4 ml) were added 4-hydroxymethylphenylboronic acid (189 mg, 1.24 mmol), potassium carbonate (517 mg, 3.74 mmol) and water (8.2 ml), which was deaerated under reduced pressure, followed by argon substitution. Tetrakis(triphenylphosphine)-palladium (73.5 mg, 0.0636 mmol) was then added, followed by heating to reflux for 5 hours under argon atmosphere. After completion of the reaction, the reaction solution was concentrated under reduced pressure. The resulting residue was subjected to reversed phase column chromatography (column; Megabond Elut™ C18 (manufactured by Varian, Inc.), eluent; acetonitrile:water=0:1→1:4 (VAT), then methanol), and fractions containing the desired compound were concentrated under reduced pressure to afford the title compound (97.7 mg) as a slightly brown solid. (Yield: 64%)
