Sodium hydride → 1-[(2'-t-Butoxycarbonylbiphenyl-4-yl)methyl]-2-butyl-4-propionylimidazole-5-carbonitrile

Participants

Reaction Steps

Following a procedure similar to that described in Example 45(a) but using 0.923 g of 2-butyl-4-propionylimidazole-5-carbonitrile (prepared as described in Preparation 25), 1.56 g of t-butyl 4'-(bromomethyl)biphenyl-2-carboxylate and 196 mg of sodium hydride (as a 55% w/w dispersion in mineral oil) in 20 ml of N,N-dimethylacetamide, 1.84 g of the title compound were obtained as a viscous oil.
