Reaction Steps

1 g of 1-benzylideneamino-2-methylthio-2-imidazoline in the form of a hydrochloride in 10 ml of methanol are treated with 0.33 ml of NH3 (28% in H2O). The mixture obtained is refluxed for ca. 5 hours and a precipitate obtained is filtrated off. From the filtrate obtained the solvent is evaporated off. The residue obtained is treated with acetonitrile. The precipitate obtained is filtrated off and dried. Solid 2-amino-1-benzylideneamino-4,5-dihydro-1H-imidazole in the form of a hydrochloride is obtained.
