85 °C

At 50° C., 1.95 g (7.02 mmol) of N-(5-bromopyridin-3-yl)benzamide, 2.00 g (10.5 mmol) of [3-(trifluoromethyl)phenyl]boronic acid and 1.49 g (14.04 mmol) of sodium carbonate were dissolved in 12 ml of 1,2-dimethoxyethane, 3.5 ml of water and 261 ml of DMF. The mixture was flushed with argon, 41 mg (0.04 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 under reduced pressure and the residue was purified by column chromatography (cyclohexane/ethyl acetate 2:1). Yield: 860 mg (35% of theory)
