Reaction Conditions

Reaction Steps

Under a nitrogen atmosphere, a mixture of 5-bromo-N-methoxy-N-methylpyridine-2-carboxamide (2.76 g), 4-chlorophenylboronic acid (2.113 g), 1,1′-bis(diphenylphosphino)ferrocene-palladium(II)dichloride dichloromethane complex (0.920 g), sodium carbonate (3.58 g), toluene (43.3 mL) and water (13 mL) was stirred at 100° C. overnight. To the reaction mixture was added water at room temperature, the mixture was extracted with ethyl acetate, and the extract was washed with water and saturated brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure and the residue was fractionated by HPLC(C18, mobile phase: water/acetonitrile (10 mM ammonium hydrogencarbonate-containing system)), the solvent was evaporated under reduced pressure, and the residue was extracted with ethyl acetate. The extract was washed with water and saturated brine, dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure to give the title compound (1.242 g).
