Procedure

A [1,1-bis-(diphenylphosphino)-ferrocene]dichloropalladium(II) dichloromethane complex (0.74 g) was added to a solution of compound (1c) (2.0 g), quinoline-3-boronic acid (2.5 g), and an aqueous sodium carbonate solution (1 M, 18 mL) in 1,4-dioxane (45 mL) under a nitrogen atmosphere, followed by stirring at 100° C. for 3 hr. The reaction solution was distributed between ethyl acetate and water, and the organic layer was washed with saturated saline and then dried over anhydrous sodium sulfate. After distillation of the solvent, the residue was purified by neutral silica gel column chromatography (chloroform/methanol) to obtain compound (1d) (0.94 g, 33%) as a white solid.
