실험 절차

At 50° C., 1.4 g (4.9 mmol) of N-(5-bromopyridin-3-yl)benzamide, 1.0 g (5.9 mmol) of [3-(1-methylethyl)phenyl]boronic acid and 1.4 g (9.9 mmol) of potassium carbonate were dissolved in 15 ml of 1,2-dimethoxyethane, 5 ml of water and 30 ml of DMF. The mixture was flushed with argon, 29 mg (0.03 mmol) of tetrakis(triphenylphosphine)palladium(0) were added and the mixture was stirred at 85° C. for 12 h. The reaction mixture was concentrated slightly on a rotary evaporator, diluted with water and extracted with dichloromethane. The organic phase was concentrated and then purified by preparative HPLC (Reprosil C18, water/acetonitrile gradient). Yield: 1.4 g (92% of theory)
