摘要

Process for the Industrial Synthesis of the compounds of formula (i): Where R and R ', that are the same or different and each represents an alkyl group (C1 - C6) linear or branched. The application to the synthesis of Bivalent Salt of ranelic acid and more particularly of Strontium Ranelate and Their carbohydrate.
