Versuchsvorschrift

1,1′-Bis (diphenylphosphino)ferrocenedichloro palladium(II) (8 mg, 0.09 mmol) was added to a suspension of the product of example 87 (100 mg, 0.19 mmol), 3-hydroxyphenylboronic acid (52 mg, 0.038 mmol) and sodium carbonate (40 mg, 0.038 mmol) in tetrahydrofuran (5 mL) and water (1 mL) and the mixture was heated at 60° C. for 12 hours. The suspension was allowed to cool to room temperature and then evaporated to dryness under reduced pressure. The residue was purified by chromatography on silica gel, eluting with dichloromethane:methanol:0.88 ammonia, 99:1:0 to 98:2:0.2, to give the title compound as a gum in 72% yield.
