Reaction Steps
To a mixture of 4-fluorobenzonitrile (12.61 g, 104 mmol) and 4-bromo-3-methylaniline (15.36 g, 82.56 mmol) in N,N-dimethylformamide (160 mL) on an ice water bath under a nitrogen balloon was added potassium tert-butyloxide (18.53 g, 165.12 mmol) portionwise. The reaction was stirred at room temperature overnight. Then water was added, and the mixture was extracted with ethyl acetate. The organic layer was washed with water, brine and dried on anhydrous sodium sulfate. The solvent was removed under reduced pressure to get crude product. The crude was then recrystallized from ethyl acetate to give 4-(4-bromo-3-methylphenylamino)benzonitrile (5.675 g, 24%).
