A solution of 4-[2-(2,2,2-trifluoroethyl)guanidino]-2-(3-aminopropylthio)pyrimidine (0.31 g.) in acetonitrile (5 ml.) was treated with 1-methylamino-1-methylthio-2-nitroethylene (0.15 g.) and the mixture heated under reflux for 18 hours. The hot solution was filtered and cooled and the solid which crystallised was collected and recrystallised from ethanol to give 1-[3-(4-[2-(2,2,2-trifluoroethyl)guanidino]pyrimid-2-ylthio)propylamino]-1-methylamino-2-nitroethylene (0.11 g.), m.p. 189°-191°.
