Versuchsvorschrift
The starting material, 4-methyl-2-imidazolin-2-ylhydrazine hydrochloride, is prepared as follows: 4-methylimidazolidin-2-thione and methyl iodide react in refluxing ethanol to give 4-methyl-2-methylthio-2-imidazoline hydroiodide, which upon treatment with hydrazine in boiling ethanol yields 4-methyl-2-imidazolin-2-ylhydrazine hydroiodide. Subsequent treatment with silver chloride in aqueous or ethanol solution then gives the hydrochloride salt melting at 128°-130° C.
