Reaction Steps

A typical but not limiting example represents a reaction of 2-(1-propyl-4 methyl-6-(1′-methylbenzimidazole-2-yl)benzimidazole with 4-bromomethyl-2′-formylbiphenyl in N,N-dimethylacetamide with potassium tert-butoxide or potassium carbonate or sodium hydroxide as a base to give 4′-[(2-n-propyl-4-methyl-6-(1-methyl-imidazol-4-yl)-benzimidazol-1-yl)methyl]-biphenyl-2-carboxaldehyde. In another typical but not limiting example 4-bromomethyl-2′-formylbiphenyl reacts in similar conditions with 2-butyl-4,4-tetramethylene-4,5-dihydroimidazol-5-one to give 2-butyl-4,5-dihydro-1-((2′-formyl-4-biphenylyl)methyl)-4,4-tetramethyleneimidazol-5-one.
