Reaction Steps
65.6 g of ethoxycarbonyl isothiocyanate were added to a mixture of 50.1 g of cyclohexanol, 100 ml of tetrahydrofuran and 10 ml of triethylamine and the mixture was refluxed for 20 hours after which the tetrahydrofuran was distilled under reduced pressure. Ether was added to the residue and the ether phase was extracted with aqueous potassium hydroxide solutions. The aqueous phase was recovered by decanting and was acidified with N hydrochloric acid. The aqueous phase was extracted with ether and the ether phase was dried and concentrated to dryness under reduced pressure to obtain 82 g of cyclohexyl N-carbethoxy-thiocarbamate. The product was purified by chromatography over silica gel with elution with an 8-2 cyclohexane-ethyl acetate mixture.
