Share. Share on. Facebook. 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. Telcagepant, is not in stock, may be available through custom synthesis.

The | Find, read and cite all the research you Telcagepant (code name MK-0974) is a calcitonin gene-related peptide receptor antagonist which was an investigational drug for the acute treatment and prevention of migraine, developed by Merck & Co.. In the acute treatment of migraine, it was found to have equal potency to … A highly efficient, asymmetric synthesis of telcagepant (1), a CGRP receptor antagonist for the treatment of migraine, is described. This synthesis features the first application of iminium Telcagepant (1) is synthesized by a coupling reaction of two heterocyclic components 2 and 3 (Scheme 1).8 While an efficient and practical synthesis of the piperidine piece 3 was recently established in our laboratories,9 there remained a need for a better synthesis of the caprolactam component 2.

This environmentally responsible synthesis contains all of the elements required for a manufacturing process and prepares telcagepant (1) with the high quality required for pharmaceutical use.

CGRP and its receptors are found in areas of the central and peripheral nervous system that are important for the transmission of The first large-scale application of asymmetric iminium ion catalysis has been reported by Xu et al. at Merck as a key step in an improved process for synthesis of telcagepant (68, Scheme 12), a calcitonin gene-related peptide (CGRP) receptor antagonist indicated for the treatment of acute migraine. 67 A first generation route to the API suitable for pilot plant manufacturing had previously been developed (Scheme 12).
