Efficient synthesis of 2-arylamino substituted pyridinyl nitriles by Buchwald–Hartwig amination
摘要:
Both nitrile and arylamino groups containing pyridine derivatives are synthesized from commercially available nitrile substituted pyridyl chlorides via a palladium-BINAP catalyst (the second generation catalyst for the amination) in moderate to good yields. The mild conditions permit the presence of base sensitive functional groups. Noteably, the halogen atoms linked to the aromatic ring were maintained in the structures of the products under the amination reaction conditions. (C) 2013 Elsevier Ltd. All rights reserved.

Novel diarylamine-substituted quinolone compounds and pharmaceutical compositions, certain of which have been found to inhibit inducible NOS synthase have been discovered, together with methods of synthesizing and using the compounds including methods for the treatment of iNOS-mediated diseases in a patient by administering the compounds.
