A simple one-pot procedure for the direct N,N-dibenzylation of anilines using a catalytic amount of Cu modified montmorillonite-KSF is described. Cu modified montmorillonite-KSF has been proven to be a simple, efficient, mild, convenient, and effective catalyst for the selective benzylation of anilines with benzyl bromide. Cu loading plays a significant role in product yield and solvents were found to control the selectivity. The catalyst is easy to prepare, heterogeneous, stable, and easy to recover.
