A Simple Synthesis of some new 2-Amino-4-hydroxybenzonitriles 4- Aminosalicylic acid derivatives are decarboxylated to the 2-amino-4-hydroxybenzonitriles 2 by heating in quinoline at 170 180°C. The bromo and iodo derivatives of 2 are prepared by nuclear bromination and reaction with iodine in the presence of iodic acid.
