실험 절차

Water (0.1 ml), potassium carbonate (48 mg) and tetrakis(triphenylphosphine)palladium (13 mg) were added to a solution of the compound obtained in Step 1 of Example 43 (61 mg) and 2-methyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridine (28 mg) in 1,4-dioxane (1.2 ml), and the mixture was stirred at 100° C. for six hours. After leaving to cool, the reaction solution was diluted with chloroform. The organic layer was washed with water and then 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->10:1 (v/v)] to give 24 mg of the title compound as a solid.
