ethyl N-(C-methoxycarbonimidoyl)carbamate → N-carbethoxy-N'-[2-((4-methyl-5-imidazolyl)methylthio)ethyl]guanidine

Participants

Reaction Steps

A solution of N-carbethoxy-O-methylisourea (1.46 g.) and 4-methyl-5-((2-aminoethyl)thiomethyl)imidazole (1.71 g.) in methanol (25 ml) was stirred at room temperature for 7 days. The white solid formed during the reaction was collected and recrystallised from methanol to give N-carbethoxy-N'-[2-((4-methyl-5-imidazolyl)methylthio)ethyl]-guanidine m.p. 196°-197°.
