Procedure

To a solution of 2-phenyl-benzo[d][1,3]oxazin-4-one (5 mmol) in dry CH2Cl2 (20 mL) was added 1N solution of aryl magnesium bromide in THF (5 mL) at 0° C. The mixture was stirred at room temperature for 2 h and poured into water (30 mL). The aqueous layer was extracted with ethyl acetate (3×30 mL) and was washed with water (3×50 mL), brine (1×50 mL), dried (anhydrous Na2SO4) and concentrated in vacuo to afford N-(2-benzoyl-phenyl)-benzamide in 60-70% yield.
