ABSTRACT
Aminomethylation at ortho position was performed with respect to hydroxyl group of m-cresol in the presence of carefully dried 4 0A molecular sieves under neat conditions. One pot, two components, Mannich reaction of m-cresol with imine at 600C under Solvent-free conditions affords the corresponding aminomethylated products in good yields, with moderate stereoselectivity.
