- Synthesis of 2-(arylamino)nicotinic acids in high-temperature water
-
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.

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