PROCESSES FOR PREPARING RALTEGRAVIR AND INTERMEDIATES IN THE PROCESSES

摘要

The present invention provides a process for preparing benzyl-2-(4-(4- fluorobenzylcarbamoyl)-5-hydroxy-1-methyl-6-oxo-1,6-dihydropyrimidin-2-yl)propan-2- ylcarbamate (RLT-8), a process for preparing Raltegravir via RLT-8, a process for preparing methyl 2-(2-(benzyloxycarbonylamino)propan-2-yl)-5 -hydroxy-1-methyl-6- oxo-1,6-dihydropyrimidine-4-carboxylate (RLT-7'), a process for preparing Raltegravir via RLT-7', and a process for preparing crystalline form V of Raltegravir potassium.
