2-[(4-Nitrophenyl)thio]-1H-imidazole → HCID 23080269, compound

Participants

Reaction Steps

To acrylonitrile (10 ml) suspension of 2-(4-nitrophenylthio)imidazole (500 mg) was added 1,8-diazabicyclo[5.4.0]undecene-7 (0.04 ml), the reaction mixture was stirred for 1 hour under refluxing. The residue obtained by concentration was purified by use of a basic silica gel column chromatography (eluent: dichloromethane), the thus obtained solid was recrystallized from dichloromethane-tert-butylmethyl ether, there was obtained 1-(2-cyanoethyl)-2-(4-nitrophenylthio)imidazole (454 mg, yield: 74%) as colorless granular product.
