Sodium borohydride → 4-(1-Hydroxy-2-methylpropyl)-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(b), but using 1.60 g of 4-isobutyryl-2-propyl-1-{4-[2-(trityltetrazol-5-yl)phenyl]phenyl}methylimidazole-5-carbonitrile [prepared as described in step (a) above] and 0.13 g of sodium borohydride, 1.50 g of the title compound was obtained as crystals, melting at 154°-155° C.
