Reaction Steps

A mixture of palladium acetate (37 mg, 0.165 mmol) and BINAP (154 mg, 0.248 mmol) in 5 mL dioxane was stirred for 10 min under Ar atmosphere. To this mixture was added 1-bromo-4-nitrobenzene (1.11 g, 5.5 mmol), 4-methoxyaniline (745 mg, 6.07 mmol), CsCO3 (2.5 g, 7.73 mmol), and 10 mL of dioxane. The mixture was heated at reflux for 15 h and cooled and diluted with ether (80 mL). The solid was removed through filtration and the filtrate was concentrated. The residue was chromatographed (hexane/EtOAc) to afford 4-methoxy-N-(4-nitrophenyl)aniline as a yellow solid (786 mg, 58%). MS (ESI) m/z 245 (M+H+).
