Thiophenol → HCID 20069003, compound

Participants

Reaction Steps

4.4 ml of thiophenol and 5.0 ml of triethylamine are added, while stirring, to a solution of 8.9 g of 2-ethylsulphinyl-3,5-dicyanothiophene, obtained according to Example I, in 100 ml of acetonitrile. After leaving to stand overnight, the reaction mixture is refluxed for 8 hours. After evaporating the solvent, the residue is taken up in methylene chloride and chromatographed over a 1 l dry silica gel column. The desired product is obtained in a yield of 9.07 g; melting-point 68°-71° C. Optionally, any 2-alkylsulphinyl compound may be used as the starting substance.
