  • Heterocyclic compounds
    Patent number: 6124312
    Abstract: The present invention provides heterocyclic 2-aza-bicyclo[2.2.1]heptane compounds which are useful for modulating a muscarinic ptor.
    Type: Grant
    Filed: June 1, 1999
    Date of Patent: September 26, 2000
    Assignee: Eli Lilly and Company
    Inventors: Charles H Mitch, Steven J Quimby, Jon K Reel, Celia A Whitesitt
  • Processes for the synthesis of unsymmetrical secondary amines
    Patent number: 5424436
    Abstract: Imines are synthesized by the hydrogenation of pyridinecarbonitriles with amines in the presence of a rhodium-loaded catalyst. The resulting imines are stable and may be transiminated and then hydrogenated to form selected secondary amine products or may be hydrolyzed to aldehydes.Further, a very useful class of unsymmetrical secondary amines represented by the formula RCH.sub.2 NHAr (in which R is not aliphatic and Ar is aromatic and not attached to R), which has heretofore been accessible only with some difficulty, can be synthesized by processes herein disclosed utilizing the reductive intermolecular coupling of nitriles and primary aromatic amines.
    Type: Grant

    Assignee: Reilly Industries, Inc.
    Inventors: Gerald L. Goe, James G. Keay, Eric F. V. Scriven, Michael L. Prunier, Steven J. Quimby
