Polysubstituted imidazoles represent a common structural motif in bioactive molecules. A modular and flexible strategy towards 2,4,5-triarylated imidazoles is reported applying a Suzuki-Miyaura cross-coupling protocol. Employing 1-protected 2,4,5-tribromoimidazole as starting material, both stepwise and one-pot protocols towards the title compounds are disclosed. The utility of the approach was demonstrated by synthesizing neurodazine, a biologically active molecule affecting neuronal cell differentiation.

Three sequential treatments of an N-protected tribromoimidazole with n-BuLi/electrophile in a 1-pot process leads to N-protected 2,4,5-trisubstituted imidazoles. The method can be applied to the preparation of the immediate of carmethizole.

1-Protected and 1,2-diprotected derivatives of 4-bromoimidazole-5-carbaldehyde were prepared from imidazole via 2,4,5-tribromoimidazole and reacted with ethyl 2-mercaptoethanoate to give the title compounds.
