A modular approach for multicomponent synthesis of amidines using modified Scolecite

•Copper exchanged Scolecite(Cu-Scolecite) was prepared by ion exchange method.•The catalytic activity of Cu-Scolecite was evaluated for multi-component synthesis of amidines.•High yields with easy recovery and reusability of catalyst were observed.

Copper exchanged Scolecite was successfully synthesized and used as an efficient, mild and recyclable catalyst for promoting multi-component synthesis of amidines from 4-toluenesulfonyl azide, phenyl acetylene and variety of substituted amines in THF at ambient temperature in good yields within short reaction time.
