Procedure

To a suspension of 0.64 g (16 mmol) 50% sodium hydride in 7.5 mL of dry dimethylformamide was added 5.7 g (16 mmol) of ethyl 3,3-bis(4-fluorophenyl)-2-(1H-tetrazol-5-yl)-2-propenoate and the resultant mixture stirred for 30 minutes. To the resultant solution, 5.7 g (18 mmol) bromotriphenylmethane was added and the mixture stirred for 24 hours. The mixture was diluted to 200 mL with water and the insolubles collected by filtration. The product was recrystallized from ethyl acetate to give 6.1 g of the title compound; m.p.=161°-162° C. (dec).
