Reaction Steps
A slurry of 1,1-bis(4-fluorophenyl)-2-(1-methyl-1H-tetrazol-5-yl)propanol (8.25 g, 0.025 mole) [prepared in Step B] and 100 mg of p-toluene sulfonic acid monohydrate in xylene (60 mL) was heated to reflux with a Dean & Stark water collecting apparatus for a period of 12 hours. The reaction mixture was washed with 1N NaOH (10 mL) while it was warm and with water (100 mL). Concentration of the organic layer gave off-white crystals of product. This was purified by recrystallization from ethanol-hexane to give 7.1 g (91%) of the title compound as white crystals; m.p.=146°-147° C.
