Procedure

A mixture of 2-chloro-4-fluorobenzonitrile (4.43 g, 28.4 mmol), 4-bromo-3-(1,3-dioxolan-2-yl)phenol (6.96 g, 28.4 mmol), and potassium carbonate (4.70 g, 34.1 mmol) in N,N-dimethylformamide (60 mL) was stirred at 100° C. under nitrogen atmosphere overnight. The mixture was poured into ethyl acetate/water. The organic layer was washed with brine and dried on anhydrous sodium sulfate. The solvent was removed under reduced pressure to give crude 4-(4-bromo-3-(1,3-dioxolan-2-yl)phenoxy)-3-chlorobenzonitrile (10.8 g), which was used for the next step without purification.
