Reaction Steps

A mixture of (4-hydroxy-2,2-dimethyl-3,4-dihydro-2H-chromen-6-yl)boronic acid (1.1 g), [1,1′-bis(diphenylphosphino)ferrocene]dichloropalladium (0.14 g) and 4′-[(5-bromo-4-ethyl-6-oxo-2-propylpyrimidin-1(6H)-yl)methyl]biphenyl-2-carbonitrile (1.5 g) in 1,4-dioxane (10 mL) and 2 M cesium carbonate (4 mL) was stirred overnight at 100° C. under an argon atmosphere. After cooling, the mixture was diluted with ethyl acetate, washed with water, dried over sodium sulfate and concentrated. The residue was purified by silica gel column chromatography to give the title compound as a colorless solid (1.5 g, 82%).
