A Newfangled Synthesis of Integrase Inhibitor Drug Substance Raltegravir Potassium

Abstract

Raltegravir sodium synthesis was achieved from its one of the key starting materials with retro synthetic approach, in which without using its critical starting material chemically known as 5-methyl-1,3,4-oxadiazole-2-carbonyl chloride and which is more unstable during the synthesis of raltegravir potassium. Almost all the existed literatures commonly using this starting material in its synthesis even it is having a stability issue and hence to achieve a stable and economically viable synthesis. The current research describes a new route of synthesis by constructing an oxadiazole ring in a retro synthetic manner.
