Procedure

[1,1′-Bis(diphenylphosphino)ferrocene]palladium(II) chloride (16 mg, 19 μmol) was added to a solution of the product of example 55 (205 mg, 0.38 mmol), 3-hydroxyphenylboronic acid (106 mg, 0.77 mmol) and sodium carbonate (81 mg, 0.77 mmol) in tetrahydrofuran (5 mL) and water (1 mL) and the mixture was heated under reflux for 16 hours. The cooled reaction mixture was then concentrated in vacuo and the residue was purified by column chromatography on silica gel, eluting with ethyl acetate:methanol, 98:2 to 96:4, to afford the title compound in 25% yield, 51 mg.
