•MCM-41-N-propylsulfamic acid was synthesized and characterized.•Synthesis of 1-amidoalkyl-2-naphthols catalyzed by MCM-41-N-propylsulfamic acid.•Used catalyst XRD and IR revealed mesopore channels was stable during reaction.
An efficient, one-pot three-component condensation of aromatic aldehydes, acetamide and 2-naphtol in the presence of catalytic amounts of MCM-41-N-propylsulfamic acid under thermal solvent-free conditions is described for the preparation of 1-amidoalkyl-2-naphtols in good to excellent yields. In this work, MCM-41-N-propylsulfamic acid was prepared by reaction of propylamine functionalized MCM-41 and chlorosulfonic acid and characterized by FTIR, XRD and TGA.
