Sodium borohydride → 2-Butyl-4-(1-hydroxy-2,2-dimethyl 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 4.03 g of 2-butyl-4-pivaloyl-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, 3.79 g of the title compound was obtained as crystals, melting at 134°-135° C.
