A simple and efficient method for the synthesis of 2,4,5-triaryl-1H-imidazole derivatives in good to excellent yields by reaction between hexamethyldisilazane and arylaldehydes, benzyl alcohols, benzyl halides in molten tetrabutylammonium bromide as an inexpensive and non toxic solvent has been developed. The remarkable advantages of this method are the simple workup procedure, high yields of products, the use of an ionic liquid as a green solvent, and the availability of reagents.
