Versuchsvorschrift
A mixture of 1,1-bis(4-fluoro-3-methylphenyl)-2-(1-methyl-1H-tetrazol-5-yl)ethanol (3.58 g, 10.9 mmoles) and potassium hydrogen sulfate (530 mg) was heated at 195° C. for 1.5 hours. The mixture was cooled to 70° C. and chloroform (50 ml) was added. The insoluble material was removed by filtration and the filtrate evaporated. The residue was crystallized from EtOAc-Hexane to afford 3.38 g (100%) of the title compound; m.p.=138°-139° C.
