Versuchsvorschrift

2-Methylthio-3-nitro-4-n-butylpyrrole (3.7 g) was suspended in glacial acetic acid (50 ml) and 30% hydrogen peroxide (1.62 g) was added. The mixture was heated to 80° for 7 hours, and it was then evaporated to a brown oil. The crude product was purified by column chromatography using silica gel, eluted with benzene and chloroform, to give an oil which crystallized on standing. This was recrystallised from 2-propanol to give 2-methylsulphinyl-3-nitro-4-n-butylpyrrole (1.6 g), m.p. 133°-4°.
