실험 절차

Under a nitrogen atmosphere a mixture of 6-chloro-N-[1-(3-methylphenyl)butyl]pyrazin-2-amine (0.21 g, 0.76 mmol), 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenol (0.23 g, 91 mmol), tetrakis(triphenylphosphine)palladium(0) (90 mg, 0.08 mmol) in toluene-n-propanol (4 mL, 3:1) was treated with 2M aqueous sodium carbonate solution (0.4 mL, 0.84 mmol). The resulting mixture was stirred vigorously whilst being heated under reflux for 22 hours. Once cool ethyl acetate was added and the mixture dried (MgSO4) and filtered. Removal of solvent in vacuo then yielded crude product, which was purified by column chromatography using dichloromethane:diethyl ether (90:10) as eluent to furnish (0.165 g, 60%).
