Versuchsvorschrift

10 g of furfurylmercaptan and 15 g of 3-penten-2-one were dissolved in 100 ml of ethanol. The solution was stirred at room temperature for 48 hours. The solvent was then distilled off in vacuo at 50° C. The residue (18 g) was purified by preparative high pressure liquid chromatography (HPLC). 9 g of 4-[(furylmethyl)thio]-2-pentanone (purity 95%) were obtained. The IR, NMR and mass spectra of the compound agree with the structure described for it.
