Procedure

A mixture of 1,1-bis(4-fluorophenyl)-2-(1-methyl-1H-tetrazol-5-yl)ethanol (4.2 g, 12.7 mmoles) [prepared in Step A] and potassium hydrogen sulfate was heated at 195° C. for 0.5 hour. After cooling, the mixture was dissolved in chloroform and washed with water. The organic layer was dried and evaporated in vacuo. The residue was triturated with diethyl ether to give 3.9 g of the title compound; m.p.=169°-171° C.
