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.
