Reaction Steps
A mixture of Example 7B (440 mg, 2.303 mmol), 4-tert-butylphenylboronic acid (492 mg, 2.76 mmol), [1,1′-bis(diphenylphosphino)ferrocene]dichloropalladium(II), complex with dichloromethane (188 mg, 0.230 mmol) and K2CO3 (637 mg, 4.61 mmol) in 1,4-dioxane (2 mL) and water (0.5 mL) was stirred at 100° C. for 16 hours. The mixture was diluted with ethyl acetate (100 mL) and washed with brine (30 mL×4). The organic layer was dried over Na2SO4, filtered and concentrated in vacuo. The residue was purified by column chromatography (on silica gel, eluted with petroleum ether/ethyl acetate=5:1, v/v) to afford the title compound (445 mg, 1.821 mmol, 79% yield) as a white solid. LC/MS (ESI) m/z 245 (M+H)+.
