実験手順

A mixture of 4′-{[3-[2-(3-bromo-4-methoxyphenyl)-2-oxoethyl]-6-ethyl-2,4-dioxo-3,4-dihydrothieno[2,3-d]pyrimidin-1(2H)-yl]methyl}biphenyl-2-carbonitrile (1.3 g), methylboronic acid (0.25 g), [1,1′-bis(diphenylphosphino)ferrocene]dichloropalladium (0.086 g), potassium carbonate (0.88 g), tetrahydrofuran (50 mL) and water (5 mL) was stirred under argon atmosphere at 50° C. for 2 days. The reaction mixture was diluted with ethyl acetate, and insoluble material was filtered off through celite. The filtrate was concentrated under reduced pressure and the obtained residue was purified by silica gel column chromatography to give the title compound as a colorless amorphous solid (0.94 g, 81%).
