N-Methylethylenediamine → HCID 178480592, compound

Participants

Reaction Steps

A mixture of 1-(2-biphenylyl)-2-methyl-2-thiopseudourea hydriodide (5.6 g) and N-methylethylenediamine (3.3 g) in ethanol (70 ml) was heated under reflux for 48 hours. Removal of the solvent gave an oil which was dissolved in methanol (25 ml) and treated with fumaric acid (1.7 g) to give 2-(1-methyl-2-imidazolidinylideneamino)biphenyl fumarate (m.p. 168°-169° C.) which was recrystallised from a 1:1 mixture of methanol and ether.
