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.

In hydrothermal reactions at 150-180 °C, 2-(arylamino)nicotinic acids were synthesized by amination of 2-chloronicotinic acid with aromatic amine derivatives, with potassium carbonate as base. The procedure is efficient, environmentally friendly, and practical, with moderate to excellent yields (up to 98%). Springer Science+Business Media B.V. 2012.
