Catalyst-free amination of 2-chloronicotinic acid in water under microwave irradiation

Abstract

A simple, efficient and environmental friendly method for the synthesis of 2-arylaminonicotinic acids derivatives by reacting 2-chloronicotinic acid with anilines with potassium carbonate as the base and water as the media under microwave irradiation is described. The synthesis of 2-arylaminonicotinic acids is important because they are nonsteroidal anti-inflammatory drugs.
