YieldReaction ConditionsOperation in experiment
With hydrogen sulfide; In N-methyl-acetamide; acetonitrile; (B) 4,5-bis(2-Thienyl)-1H-2-imidazolethiol A mixture of 12 g of 4,5-bis-(2-thienyl)-1H-imidazole, 250 ml of tetramethylene sulfone (purified), and 2.5 g of sulfur was heated at 170 C. for 24 hours in a nitrogen atmosphere, then 2 g more sulfur was added and the heating continued 19 hrs. The mixture was cooled, poured into 2 l. water, filtered, washed and dried. The dried product (9.8 g) was dissolved in dimethylformamide and poured on a column of alumina and eluted with dimethylformamide. The product came off with the first cuts, and after evaporating and stirring with acetonitrile and filtering, 5.3 g of product was obtained, melting 213-218. A thin layer chromatograph shows this to be a mixture of the starting material and the desired thiol. A small portion of the crude compound chromatographed in the same way gave 1.02 g, m.p. 283-290 C.
