Potassium ethylxanthate → HCID 12460786, compound

Participants

Reaction Steps

Twenty grams of 1-(β, 2,4-trichlorophenethyl)imidazole hydrochloride was added to 300 milliliters (ml) of absolute ethanol and 25 grams of anhydrous potassium ethyl xanthate. The mixture was stirred at room temperature for about 3 days until the reaction was complete as indicated by thin layer chromatography. The solvent was removed, water added and the product extracted with ether. The extracts were washed with water, dried over magnesium sulfate and the ether evaporated. The resulting oil was purified by chromatography on silicia gel eluting with 15% acetone in dichloromethane. The resulting oil was then dissolved in ether and an ethereal solution of oxalic acid was added dropwise until precipitation was complete. Recrystallization of the precipitate from acetone provides the oxalate salt of 1-[2,4-dichloro-β-(ethoxythiocarbonylthio)phenethyl]imidazole as a white solid having a melting point of 122.5°-124° C. (foaming).
