実験手順

Triethylamine (1.2 mL, 8.4 mmol) was added to a suspension of ethyl 3-(4-(5-aminopyridin-2-yloxy)phenyl)propionate (1.2 g, 4.2 mmol), 3,4-dichlorophenylboronic acid (1.6 g, 8.4 mmol), anhydrous copper acetate (0.762 g, 4.2 mmol) and molecular sieves 4A (5 g) in dichloromethane (24 mL), and the resulting reaction solution was stirred overnight at room temperature. After the resulting solution was filtered through Celite, the filtrate was concentrated under reduced pressure. The residue was purified by silica gel chromatography (n-hexane:ethyl acetate=4:1), to thereby yield 1.5 g of the title compound.
