Five reaction tubes each containing 5-chloropyridazin-3(2H)-one (100 mg, 0.77 mmol), 4-methoxyphenylboronic acid (230 mg, 1.53 mmol), dioxane (3 ml), 2M aqueous sodium carbonate solution (1 ml) and [1,1′-bis(diphenylphosphino)ferrocene] dichloropalladium (20 mg) were irradiated in a microwave reactor at 150° C. for 10 minutes. After cooling to room temperature the mixtures were combined and filtered. The collected solid was washed with water (3 ml), ethyl acetate (5 ml) and ether (5 ml), then dried to give the title compound (724 mg, 93%).
