potent inhibitors of the human immunodeficiency virus type I (HIV-I) reversetranscriptase. Diarylpyridines like Etoricoxib has been introduced as a selective COX-2 inhibitor. In continuation of our work on diaryl heterocycles for biological evaluation, we report herein the synthesis of some new heterocyclic substituted pyridines under microwave conditions. Thus microwave irradiation of various enaminoketones
