Versuchsvorschrift
A mixture of 1-[4-Methyl-2-(4-trifluoromethyl-phenyl)-thiazol-5-yl-]-ethanol (1.0 g, 3.48 mmol) and MnO2 (0.45 g, 5.22 mmol) in chloroform (30 mL) is heated to reflux, after 24 hrs, additional MnO2 (300 mg) is added and refluxed for another 9 hrs, the reaction mixture is filtered through celite. Concentration of filtrate gave the title compound (1.0 g).
