Procedure

A solution of 4-methyl-5-[(2-aminoethyl)thiomethyl]imidazole (1.7 g.) and S-methyl-N-nitroisothiourea (1.45 g.) in methanol (35 ml.) was heated at 50°-60° for 2.5 hours and then set aside at room temperature for 48 hours. The crystalline product was filtered off and recrystallised from methanol to give N-[2-((4-methyl-5-imidazolyl)methylthio)ethyl]-N'-nitroguanidine, m.p. 184°-186°.

Workup

  1. filtrationThe crystalline product was filtered off
