Procedure

The general procedure of Example 8 was repeated, except that the 3,3-bis(4-fluorophenyl)-2-(1-methyl-1H-tetrazol-5-yl)-2-proenal utilized therein was replaced by 0.67 g (21.0 mmoles) of 3,3-bis(4-fluorophenyl)-2-(2-methyl-2H-tetrazol-5-yl)-2-propenal [prepared in Example 7]. The reaction was carried out with 0.64 g (21.0 mmoles) of triphenylphosphoranylidene acetaldehyde to yield 0.66 g (90.5%) of the title compound.
