Following a procedure similar to that described in Example 74(b), but using 2.00 g of 2-butyl-4-isobutyryl-1-{4-[2-(trityltetrazol-5-yl)phenyl]phenyl}methylimidazole-5-carbonitrile [prepared as described in step (a) above] and 0.22 g of sodium borohydride, 1.68 g of the title compound was obtained as crystals, melting at 127°-128° C.
