실험 절차
In a similar manner to that described in Example 272, N-(5-chloro-2-morpholinophenyl)cyanamide (2.3 g) in ethanol (10 ml) and a 33% ethanolic solution of dimethylamine (6 ml) were heated under reflux for 4 hours to give 1,1-dimethyl-2-(5-chloro-2-morpholinophenyl)guanidine (m.p. 135°-138° C.) which was recrystallised from hexane and then was converted into its monofumarate salt (m.p. 223°-225° C.) which was recrystallised from methanol.
