実験手順

Into toluene (10 ml), 2-(trimethylsilyl)ethyl 4-{[(trifluoromethyl)sulfonyl]oxy}isoquinoline-6-carboxylate (500 mg, 1.2 mmol) was dissolved, to which 4-{2-[4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenoxy]ethoxy}tetrahydro-2H-pyran (630 mg, 1.8 mmol) synthesized in Reference Example 2, 4,5-bis(diphenylphosphino)-9-dimethylxanthene (210 mg, 0.36 mmol), tris(dibenzylideneacetone)palladium (160 mg, 0.17 mmol), and potassium carbonate (500 mg, 3.6 mmol) were added. The resulting mixture was stirred at 100° C. for four hours, to which ethyl acetate was added. The resulting mixture was sequentially washed with water and saturated brine, and then dried over anhydrous sodium sulfate and concentrated under reduced pressure. The residue thus obtained was purified by silica gel column chromatography (hexane:ethyl acetate, 100:0-50:50, V/V) to give the desired title compound (307 mg, yield 52%).
