Versuchsvorschrift
2-(4-Tert-butylbenzyl)thio-3-tosyloxymethyl chromen-4-one (3 g, 5.9 mmol) is introduced into a 15 mL round bottom flask and tetrabutylammonium fluoride solution (5.9 mmol; 1M in THF) is added to it. The solution is heated to reflux for 3 hours after which all volatiles are removed and the residue obtained is purified by silica gel flash chromatography (ethyl acetate:hexanes).
