Procedure

A mixture of 1,3-dimethyl-2-imidazolidinone (5.5 g) in benzene (30 ml), 2-aminobiphenyl (5.1 g) in benzene (20 ml) and phosphorus oxychloride (4.4 ml) was heated at 80°-85° C. for 20 hours to yield 2-(1,3-dimethyl-2-imidazolidinylideneamino)biphenyl (m.p. 90°-91° C.) which was recrystallised from hexane.
