Procedure

A mixture of 1-fluoro-2-nitrobenzene (13.06 g, 92.6 mmol), 2-aminobiphenyl (31.3 g, 185.2 mmol), and potassium fluoride (8.1 g, 138.9 mmol) was prepared in a 100 mL round bottom flask. The flask was evacuated and replaced with nitrogen. The mixture was heated to 200° C. overnight. The reaction mixture was cooled and ethyl acetate and water were added. The layers were separated and the aqueous layer was extracted with ethyl acetate. The organic layers were dried over magnesium sulfate, filtered, and evaporated. The residue was preabsorbed onto Celite and purified by column chromatography eluting with 0, 2, and 5% ethyl acetate/hexanes. 24.5 g (91%) of product was obtained.
