실험 절차
A vial charged with Pd2(dba)3 (0.150 g, 0.164 mmol), XPhos (0.391 g, 0.819 mmol), 5-(tributylstannyl)pyrimidine (1.81 g, 4.92 mmol), 2-bromo-7-methoxy-9H-xanthen-9-one (1.000 g, 3.28 mmol) and dioxane (10 mL). The reaction mixture was evacuated and backfilled with nitrogen. The reaction mixture was heated to 100° C. overnight. The reaction mixture was cooled to RT and diluted with water and EtOAc. A grey solid precipitated out, which was filtered off. The solid was washed with EtOAc and water. The grey solid dried under reduced pressure to afford 2-methoxy-7-(pyrimidin-5-yl)-9H-xanthen-9-one) (0.600 g, 60.2% yield).
