synthesis of annelated pyridines from cyclic ketones, aldehydes and ammonia was carried out over various zeolite molecular sieves like Hβ, HZSM-5 (240), HZSM-5 (40), HY, HX, HMCM-41 and Mordenite. The preliminary screening of catalyst clearly shows that Hβ catalyst was found to be more active for the vapor phase synthesis of annelated pyridines. Hβ was further modified with transition metals like Fe, Cu
