実験手順

A mixture of 4-(2-aminophenyl)morpholine hydrochloride (7.5 g) and n-butyronitrile (20 ml) was heated at 170° C. in a sealed stainless steel pressure vessel for 60 hours. Excess n-butyronitrile was removed and the residue dissolved in water, basified with 10% aqueous sodium hydroxide solution to pH 12 and extracted with dichloromethane. The extract was washed with water and then brine, dried and the solvent removed. The residue was purified by chromatography on a neutral alumina column. Elution with a 1:1 mixture of dichloromethane and hexane removed unreacted starting material and then elution with a 1:99 mixture of methanol and dichloromethane yielded a solid which was dissolved in methanol (10 ml) and treated with fumaric acid (0.4 g) to give N-(2-morpholinophenyl)butyramidine monofumarate (m.p. 168°-170° C.) which was recrystallised from a 1:2 mixture of methanol and ether.
