実験手順

To a solution of 2-[3-(3-bromo-pyridin-2-yl)-azetidin-1-yl]-quinoline (339 mg, 1 mmol), 3-methoxy-phenylboronic acid (167.2 mg, 1.1 mmol), K3PO4 (414 mg, 2.0 mmol) in dioxane (20 mL) and water (2 mL) was added Pd(dppf)Cl2 (36.6 mg, 0.05 mmol) then the reaction mixture was stirred at 90° C. under nitrogen atmosphere overnight. The reaction mixture was filtered through CELITE® and washed with EtOAc (50 mL). The filtrate was concentrated and the crude product was purified by ISCO silica gel column (10% to 80% EtOAc in petroleum ether) to give 2-{3-[3-(3-methoxy-phenyl)-pyridin-2-yl]-azetidin-1-yl}-quinoline (132 mg, 0.36 mmol, yield 36%).
