HCID 15461993Ethyl 1-((2'-cyano(1,1'-biphenyl)-4-yl)methyl)-4-(1-hydroxy-1-methylethyl)-2-propyl-1H-imidazole-5-carboxylateYield 95.3%

Procedure

Following a procedure similar to that as described in Example 68(a), but using 4.01 g of ethyl 4-(1-hydroxy-1-methylethyl)-2-propylimidazole-5-carboxylate (prepared as described in Preparation 9), 5.0 g of 4'-bromomethylbiphenyl-2-carbonitrile and 1.97 g of potassium t-butoxide, 6.86 g of the title compound were obtained as crystals, melting at 92°-93° C.
