Versuchsvorschrift
1.25 g sodium is allowed to react with 150 ml absolute methanol. When all the sodium has disappeared, one adds 6 ml benzylmercaptan and 13.5 g 4-chloro-3-formyl-flav-3-ene and refluxes over 15 minutes. After solvent evaporation and extraction with methylene chloride the residue is crystallized in a mixture of hexane and diisopropylether. Pure 4-benzylmercapto-3-formyl-flav-3-ene is obtained as yellow crystals; m.p. 99°-100° C.
