In this work, an efficient, user‐friendly, and simple procedure was reported for the preparation of indole derivatives catalyzed by the heterogeneous SBA‐15‐Pr‐SO₃H via Fischer indole pathway. The title compounds were synthesized from various arylhydrazines and ketones in the presence of 3 mol% of the catalyst in the refluxing ethanol.
