A novel series of non-peptidic OX1R/OX2R orexin receptor antagonists was prepared by heterocyclic replacement of the dimethoxyphenyl moiety contained in the tetrahydroisoquinoline core skeleton of almorexant. Introduction of substituted imidazole moieties delivered potent dual orexin receptor antagonists with nanomolar potency for hOX1R and hOX2R suitable for further fine-tuning. The preparation of
