Procedure

2-Methylsulphinyl-3-nitro-4-phenylpyrrole (2.0g, 0.008 mol) was partially dissolved in ethanol (150 ml) and a solution of 2-(5-methyl-4-imidazolylmethylthio)ethylamine (1.37g, 0.008 mol) in a little ethanol was added to it. The mixture was refluxed for seven days, after which the mixture was stripped and chromatographed on a silica gel column, collecting the required product by elution with ethyl acetate. The crude solid was recrystallised from 2-propanol to give 2-[2-(5-methyl-4-imidazolylmethylthio)ethyl]amino-3-nitro-4-phenylpyrrole (0.46g), m.p. 182-184'.
