keywords = {In recent years; significant interest has been devoted to the preparation of substituted indoles due to their varied biological activities including antioxidant; antibacterial; and insecticidal. They also act as colon cancer cell and tumor growth inhibitors and are employed as valuable antibiotics.[1;2] 
Despite several methods available in the literature for the synthesis of substituted indoles; there are only a few reports on the access of substituted 3-aminoalkylated indoles using Multi Component Reactions (MCR) protocols.[3;4] 
In this work three-component reactions of indoles; benzaldehydes and N-alkylanilines in the presence of an acid catalyst; such as ferric hydrogensulfate (FHS) as a recyclable; easy synthesized and inexpensive catalyst.(Scheme 1) 
Decreasing of reaction times; increasing of isolated yields; low percent of bisindolylmethaneformation as byproduct and solvent free conditions are the benefits of this method by means of FHS as catalyst.},
