Sodium hydride → HCID 13208971, compound

Participants

Reaction Steps

(b)(ii) A solution of 1-nitro-2-methylthio-2-(2-bromoethylamino)ethylene (3 g, 0.012 mol) and sodium hydride (50% in oil, 0.62 g, 0.013 mol) in dry tetrahydrofuran (100 ml) was refluxed for 7 hours. The reaction mixture was cooled, and the solvent was removed in vacuo. The residue was extracted with boiling ethyl acetate (2×50 ml), and the extracts were decolourized with charcoal. Concentration of the extracts in vacuo, followed by cooling, resulted in the crystallisation of 2-methylthio-3-nitro-4,5-dihydropyrrole (0.5 g, 26%).
