Procedure

To a suspension of 1-methylimidazolidine-2-thione (5.17 g, 44.5 mmol) in acetone (50 mL) was added MeI (2.9 mL, 46.6 mmol). The solution was allowed to stir at room temperature for 4 h and the resulting solid was quickly filtered and then dried in vacuo to give 1-methyl-2-(methylthio)-4,5-dihydro-1H-imidazole hydroiodide (8.79 g, 77%) as beige solid.
