Reaction Conditions

Reaction Steps

Water (0.1 ml), potassium carbonate (70 mg) and [1,1′-bis(diphenylphosphino)ferrocene]palladium(II) dichloride-dichloromethane adduct (6.9 mg) were added to a solution of the compound obtained in Step 1 of Example 31 (95 mg) and 2-methoxy-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenol (51 mg) in 1,4-dioxane (1.5 ml), and the mixture was stirred at 100° C. for four hours. After leaving to cool, the reaction solution was diluted with ethyl acetate. The organic layer was washed with water and brine and dried over sodium sulfate. The solvent was distilled off under reduced pressure, and the residue was purified by silica gel column chromatography [chloroform:methanol=300:1->30:1 (v/v)] to give 43 mg of the title compound as a solid.
