Efficient and Green Protocol for the Synthesis of Hippuric Acid

The main aim of the green chemistry to addresses various concerns related to minimization of hazardous chemicals, use of safer green chemicals, catalyst and solvent. A One pot synthesis of Hippuric acid has been achieved starting from Glycine and Benzoyl chloride in the presence of Potassium carbonate as a Green base and Tartaric acid, Citric acid as a Green acid. The recent environmental concerns, we developed the most economical efficient and environmental friendly protocol for the synthesis of Hippuric acid in very good yield (greater than81%).
