Reaction Steps

20.0 g (0.075 mol) of 4,4,8-trimethyl-1,1-dioxothiochroman-7-carboxylic acid were dissolved in 200 ml of toluene and three drops of dimethylformamide and 10.7 g (0.09 mol) of thionyl chloride were added. After three hours of heating under reflux, the solvent was removed and the colorless oil that remained (yield 21.3 g) was directly used further.
