Reaction Steps

Under nitrogen atmosphere, a solution of Na2CO3 (220 mg) in water (1.6 ml) was added to a suspension of 6-(5-amino-6-bromo-3-phenyl-2-pyrazinyl)-2-isopropyl-3(2H)-pyridazinone (200 mg), phenylboronic acid (158 mg) and tetrakis(triphenylphosphine)palladium (18 mg) in dioxane (6 ml) and the mixture was stirred at 100-105° C. for 2 hours. After addition of water (6 ml), a precipitate was collected by filtration and purified by column chromatography on silica gel eluting with a mixture of n-hexane and EtOAc (60:40 v/v) to give a solid. The solid was suspended in acetone and collected by filtration to give 6-(5-amino-3,6-diphenyl-2-pyrazinyl)-2-isopropyl-3(2H)-pyridazinone (150 mg).
