実験手順

The compound obtained in Step 2 of Example 41 (2.05 g), 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)aniline (1.14 g), tetrakis(triphenylphosphine)palladium (0.3 g), and potassium carbonate (2.15 g) were suspended in dioxane (30 ml) and water (6 ml), and the suspension was stirred at 100° C. for two hours. After leaving to cool, the reaction solution was diluted with chloroform, followed by washing with water. The organic layer was dried over anhydrous sodium sulfate. The solvent was distilled off under reduced pressure, and the residue was purified by silica gel column chromatography [ethyl acetate:hexane=1:1->chloroform:ethanol=19:1 (v/v)] to give 1.27 g of the title compound as a solid.
