Procedure
A mixture of 2-amino-4'-methylbiphenyl hydrochloride (5.3 g), N,N-dimethylcyanamide (2.55 g) and m-cresol (25 ml) was heated at 90°-95° C. for 10 hours to give N,N-dimethyl-N'-(4'-methyl-2-biphenylyl)guanidine (m.p. 147°-148° C.) which was recrystallised from hexane.
Workup
- temperaturewas heated at 90°-95° C. for 10 hours
