  • Publication number: 20150112067
    Abstract: The disclosure encompasses a novel process for making piperidinone carboxamide indane and azainane derivatives, having less steps and improved yields as compared to previous synthetic methods for making these compounds, which are CGRP receptor antagonists, useful for the treatment of migraine. Conditions for an amide bond formation between an acid and amine include for example reacting the compounds of Formulae B (after salt break) and C with an amide coupling reagent and optionally an additive and an acid and/or a base in a non-reactive solvent.

  • Patent number: 8329905
    Abstract: This application discloses a novel process for the preparation of phosphonate esters useful as intermediates in the preparation of himbacine analogs, themselves useful as thrombin receptor antagonists. The chemistry taught herein can be exemplified by the following scheme: wherein R9 is selected from alkyl, aryl heteroaryl and arylalkyl groups having 1 to 10 carbon atoms, and R11 is selected independently for each occurrence from alkyl, aryl heteroaryl and arylalkyl groups having 1 to 10 carbon atoms and hydrogen, X2 is Cl, Br, or I; X3 is selected from Cl and Br; and PdLn is a supported palladium metal catalyst or a soluble heterogeneous palladium catalyst. The L-derivatizing reagent is a moiety which converts the alcohol functional group of compound 137D to any leaving group which can be displaced by a triorgano-phosphite phosphonating agent.
