A convenient method was developed to prepare the diastereomer of dolutegravir tricyclic intermediate in the catalysis of EDCI/DMAP in up to 87% yield. Different solvents, temperature, and times were optimized. The synthesized diastereomer 6′ could be used as a standard for the industrial manufacture requirement of dolutegravir active pharmaceutical ingredient.
