Abstract: The present disclosure provides improved processes for the preparation of Relugolix and intermediates thereof. Relugolix is prepared via intermediates (M7) and (M8): wherein X is as described herein. Present disclosure also provides three additional routes to prepare Relugolix and intermediates thereof, where the starting material of ethyl 2-amino-4-methyl-5-(4-nitrophenyl)thiophene-3-carboxylate (SM1) is protected by coupling with an acyl chloride, a hydroxylamine or an oxime.

Abstract: The present invention provides improved processes for purifying liraglutide. Liraglutide is purified via two sequential RP-HPLC purifications followed by a salt-exchange step, where a pH is kept constant in the first and second purification steps. In particular, the processes utilize a halogenated solvent in a sample preparation step, which provides better solubility and an environment suitable for decarboxylation for crude liraglutide prior to a RP-HPLC purification.

Abstract: The present invention provides improved processes for the preparation of elagolix and intermediates thereof. The intermediate of formula VII is achieved by a coupling reaction of a compound of formula V and a N-benzylidene protected compound of formula IV: The present invention is suitable for a large-scale production, avoiding the use of potential genotoxic substances and can be performed under mild conditions.
