Procedure
A mixture of 1.0 g (4.17 mmole) of 4,4′-diaminobenzil and 0.45 g of o-phenylenediamine in 250 ml glacial acetic acid was heated at 50° C. for 15 mins., then stirred for 16 hours at room temperature. The mixture was then heated to 80° C. and allowed to cool slowly. The solvent was removed under vacuum and the residue was redissolved in ethanol and that was removed under vacuum.
