実験手順

Tert-butyl 4-bromo-2-(5-phenylpyridine-3-carboxamido)benzoate (0.11 g), sodium carbonate (64 mg), water (0.30 mL), and bis(triphenylphosphine)palladium(II) dichloride (3.5 mg) were added to an ethylene glycol dimethyl ether (1.0 mL) solution of N,N-diethyl-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)aniline (83 mg), followed by heating to reflux under a nitrogen atmosphere for 2 hours and 40 minutes. The reaction mixture was cooled to room temperature, and then water and chloroform were added thereto. The organic layer was separated and dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure. The obtained residue was purified by silica gel column chromatography [eluent: 90-70% hexane/ethyl acetate] to obtain 0.12 g of tert-butyl 4-(3-(diethylamino)phenyl)-2-(5-phenylpyridine-3-carboxamido)benzoate as a yellow solid.
