An efficient and green procedure for the synthesis of 2aminopyridines derivatives via four-component reaction of acetophenone, malononitrile, triethoxymethane and different primary amines has been developed using different surfactant-containing mesoporous catalysts. The advantages of this approach are easy operational method, high product yields and reusable catalysts without losing their catalytic activity.
