Reaction Steps

A mixture of methyl 4-(pentylamino)-1H-imidazole-5-carbimidothioate (0.53 g, 2.4 mmol) and formic hydrazide (0.21 g, 3.5 mmol) in ethanol (10 mL) was refluxed overnight. The reaction mixture was concentrated under reduced pressure to yield the desired product as a slightly green viscose oil. LCMS calculated for C10H17N6 (M+H): 221.2; found: 221.1.
