실험 절차

Into a 250-mL round bottom flask, was placed a solution of 4-chloro-2-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzenamine (3 g, 11.83 mmol, 1.00 equiv) in dioxane (120 mL), water (20 mL), 4,6-dichloropyrimidine (4.4 g, 29.53 mmol, 2.50 equiv), triphenylarsine (360 mg, 1.18 mmol, 0.10 equiv), K3PO4 (3.8 g, 17.90 mmol, 1.50 equiv), Pd(PPh3)2Cl2 (390 mg, 0.56 mmol, 0.05 equiv). The resulting solution was stirred for 3 h at 75° C. in an oil bath. The resulting mixture was concentrated under vacuum. The residue was applied onto a silica gel column with ethyl acetate/petroleum ether (1:50˜1:10). This resulted in 1.5 g (53%) of 4-chloro-2-(6-chloropyrimidin-4-yl)benzenamine as a yellow solid.
