Procedure
Following a procedure similar to that described in Example 74(a), but using 1.42 g of 2-butyl-4-isobutyrylimidazole-5-carbonitrile (prepared as described in Preparation 27) 4.49 g of 4-[2-(trityltetrazol-5-yl)phenyl]benzyl bromide and 0.76 g of potassium t-butoxide. 3.04 g of the title compound was obtained as crystals, melting at 115°-116° C.
