Reaction Conditions:

with p-nitrobenzenesulfonic acid;palladium diacetate in tetrahydrofuran;water at 80; for 48 h;Inert atmosphere;Schlenk technique;

Steps:

General Procedure for the Synthesis of o-Aminobenzophenones
General procedure: Under a N₂ atmosphere, a Schlenk tube was charged with 2-aminobenzonitrile 1 (0.3 mmol),sodium arylsulfinate 2 (0.6 mmol), Pd(OAc)₂ (10 mol %), bpy (20 mol %), p-NBSA (10 equiv), THF (2 mL), and H₂O (1 mL) at room temperature. The reaction mixture was stirred vigorously at 80 °C for 48 h. The mixture was poured into ethyl acetate, which was washed with saturated NaHCO₃ (2 × 10 mL) and then brine (1 × 10 mL). After the aqueous layer was extracted with ethyl acetate, the combined organic layers were dried over anhydrous MgSO₄ and evaporated under reduced pressure. The residue was purified by flash column chromatography (hexane/ethyl acetate) to afford the desired products 3.
