Procedure
Following a procedure similar to that described in Example 35(a), but using 0.50 g of dimethyl 2-butylimidazole-4,5-dicarboxylate (prepared as described in Preparation 4) and 1.17 g of 4-[2-(trityltetrazol-5-yl)phenyl]benzyl bromide, 0.51 g of the title compound was obtained as an amorphous solid.
