Sodium hydride → 1-[(2'-t-Butoxycarbonylbiphenyl-4-yl)methyl]-2-butyl-4-(1-hydroxy-2-methyl-1-(1-methylethyl)propyl]imidazole-5-carbonitrile

Participants

Reaction Steps

Following a procedure similar to that described in Example 45(a), but using 282 mg of 2-butyl-4-[1-hydroxy-2-methyl-1-(1-methylethyl)propyl]imidazole-5-carbonitrile (prepared as described in Preparation 30), 409 mg of t-butyl 4'-(bromomethyl)biphenyl-2-carboxylate and 47 mg of sodium hydride (as a 55% w/w dispersion in mineral oil) in 5 ml of N,N-dimethylacetamide, 513 mg of the title compound were obtained as a viscous oil.
