Procedure

A mixture of 2-methyl-1-(6-methyl-2-morpholinophenyl)-3-methyl-2-thiopseudourea hydroiodide (17.8 g), n-butylamine (6.4 g) and ethanol (60 ml) was stored at ambient temperature for 60 days. Potassium hydroxide (2.2 g) and then lead acetate trihydrate (7.6 g) were added and the mixture was heated under reflux for 5 hours to yield 1-(n-butyl)-2-(6-methyl-2-morpholinophenyl)-3-methylguanidine which was converted into its monofumarate salt (m.p. 203°-204° C.) which was recrystallised from a 1:2 mixture of methanol and ether.
