Procedure

A slurry of 1,1-bis(4-fluorophenyl)-2-(1-methyl-1H-tetrazol-5-yl)-1-propene (61.46 g, 0.197 mole) [prepared in Step C], N-bromosuccinimide (35.06 g, 0.197 mole) and catalytic amount of azobis isobutyronitrile or benzoyl peroxide in carbon tetrachloride (1.2 liters) was heated to reflux in an inert atmosphere for a period of 2 hours. The reaction mixture was cooled to ambient temperature and the solid from the reaction was filtered. The filtrate was concentrated under reduced pressure and the solid obtained was recrystallized from toluene-hexane to give 72 g (93%) of the title compound as white crystals; m.p.=159°-160° C.
