Participants

Reaction Steps

A mixture of 2-methyl-1-(2-morpholinophenyl)-3-methyl-2-thiopseudourea hydriodide (3.9 g prepared as described in Example 210), pyrrolidine (1 ml) and ethanol (40 ml) was heated under reflux for two weeks to yield an oil which was purified by chromatography on a neutra alumina column eluted with a 1:1 mixture of dichloromethane and hexane and then a 1:9 mixture of methanol and dichloromethane to give N-methyl-N'-(2-morpholinophenyl)pyrrolidine-1-carboxamidine which was converted into its monofumarate salt (m.p. 168°-171° C.) which was recrystallised from propan-2ol.
