Telcagepant synthesis

Telcagepant Accession Number DB12228 Description. Telcagepant has been investigated for the treatment of Migraine. It is an antagonist of the receptor for calcitonin gene-related peptide (CGRP), a primary neuropeptide involved in the pathophysiology of migraine. Telcagepant (MK0974) is one of several calcitonin-gene-related peptide antagonists in development as a potential treatment for acute migraine attacks and is the first orally available drug in this Synthesis Reference. Leonardo R. Allain, et.

Synthesis of the (3R,6S)-3-Amino-6-(2,3-difluorophenyl)azepan-2-one of Telcagepant (MK-0974), a Calcitonin Gene-Related Peptide Receptor Antagonist for the Treatment of Migraine Headache | Organic Letters. Second part of the synthesis of Telcagepant. Cyclisation involved the employment of a mixed anhydride, possible for the decreased nucleophilicity of the trifluoroethyl nitrogen, and was followed by a base promoted dynamic crystallisation process in aqueous NaOH/DMSO mixture, which allowed the isolation of the 2-acetamido caprolactam 60 in 73% overall yield from the enamide.
