14.11 g of 2-methylamino-2-methylthio-1-nitroethylene was added to a solution of 15.81 g of 4-[[(2-aminoethyl)thio]-methyl]-2-hydroxymethylthiazole in 190 ml of DMF. The solution was stirred at room temperature for 4 days. The reaction mixture was concentrated under reduced pressure to give a residue which was chromatographed on silica gel eluting with 5-10% methanol in acetonitrile to give 12.8 g (61%) of N-[2-[[[2-(hydroxymethyl)-4-thiazolyl]methyl]thio]ethyl]-N'-methyl-2-nitro-1,1-ethenediamine.
