Methyl iodide → methyl 4-(pentylamino)-1H-imidazole-5-carbimidothioate

Participants

Reaction Steps

To a solution of 4-(pentylamino)-1H-imidazole-5-carbothioamide (1.0 g, 4.7 mmol) in acetone (40 mL) was added methyl iodide (0.80 g, 5.6 mmol) dropwise. The mixture was stirred at room temperature overnight. The solvent was removed and the residue was diluted with water and ethyl acetate. The organic layer was washed with water and brine, dried and concentrated to yield the crude product (1.2 g), which was used for next step without further purification. LCMS calculated for C10H19N4S (M+H): 227.1; found: 227.1.
