Microwave-assisted synthesis of 2-aminoquinolines

An improved method for the synthesis of 2-aminoquinolines utilizing microwave-assisted synthesis is described. The process involves rapid microwave irradiation of secondary amines and aldehydes to form enamines followed by the addition of 2-azidobenzophenones with subsequent irradiation to produce the 2-aminoquinoline derivatives. Purification of the products is accomplished in a streamlined manner using solid-phase extraction techniques to produce the desired products in high yields and purity.
