Procedure
Following a procedure similar to that described in Example 40(c), 0.84 g of ethyl 2-butyl-4-(1-hydroxyethyl)-1-{4-[2-(trityltetrazol-5-yl)phenyl]phenyl}methylimidazole-5-carboxylate [prepared as described in step (a) above] was treated with 75% v/v aqueous acetic acid, to give 0.54 g of the title compound as an amorphous solid.
