Nucleophilic substitution of urea on aromatic carboxylic acids via phosphorylation

The nucleophilic substitution reaction of urea on aromatic carboxylic acids has been carried out via phosphorylation.Five different carboxylureas have been synthesised in good yields and with high purity.This new route makes the existing corrosive acid chloride route easier and can be used as a general route for the preparation of any acid-urea substitution product.The products have been characterized by elemeental analyses and spectral data (IR, PMR and mass).
