5-(4'-(Bromomethyl)(1,1'-biphenyl)-2-yl)-1-trityl-1H-tetraazole → 4-Isobutyryl-2-propyl-1-{4-[2-(trityltetrazol-5-yl)phenyl]phenyl}methylimidazole-5-carbonitrile

Participants

Reaction Steps

Following a procedure similar to that described in Example 74(a), but using 0.97 g of 4-isobutyryl-2-propylimidazole-5-carbonitrile (prepared as described in Preparation 39), 2.90 g of 4-[2-(trityltetrazol-5-yl)phenyl]benzyl bromide and 0.56 g of potassium t-butoxide, 1.90 g of the title compound was obtained as crystals, melting at 133°-134° C.
