Procedure
In a similar manner to that described in Example 286, N-(5-fluoro-2-morpholinophenyl)cyanamide (2.2 g) in ethanol (10 ml) and a 33% ethanolic solution of dimethylamine (6 ml) was heated under reflux for 20 minutes to give 1,1-dimethyl-2-(5-fluoro-2-morpholinophenyl)guanidine (m.p. 137°-138° C.) which was recrystallised from hexane and converted into its fumarate salt (m.p. 222°-224° C.) which was recrystallised from methanol.
