Procedure
A solution of 4-(2-aminophenylamino)benzophenone (Compound 101 0.29 g, 1.0 mmol) in ethyl formate (5.0 ml, 63 mmol) was refluxed for 16 hours. The reaction mixture was evaporated in vacuo and dissolved i ethyl acetate. The solution was filtered and evaporated in vacuo. The residue was crystallized on the addition of diethyl ether to afford the pure title compound.
