Procedure

1-Amino-2-hexanone hydrochloride (5.8 g) was dissolved in methanol (100 ml) and mixed with a solution of 1-methylthio-1-methylsulphinyl-2-nitroethylene (6.8 g) in warm methanol (100 ml). A solution of sodium methoxide in methanol (from 1.7 g sodium) was added dropwise, with stirring, over 2 hours at 60°, and the mixture was evaporated to dryness. The residue was triturated with water, and the solid was filtered off and dried, to give 2-methylthio-3-nitro-4-n-butylpyrrole (3.9 g).
