A mixture of 2-aminobiphenyl hydrochloride (9.2 g) and N,N-dimethylcyanamide (4.8 g) in m-cresol (30 ml) was heated at 90°-95° C. for 10 hours to yield an oil which was dissolved in methanol (60 ml) and treated with fumaric acid (4.5 g) to give N-(2-biphenylyl)-N',N'-dimethylguanidine fumarate (m.p. 175°-176° C.) which was recrystallised from a 2:3 mixture of methanol and ether.
