Abstract
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%).
