  • Solid phase preparation of amines
    Patent number: 5932696
    Abstract: A method for the solid phase preparation of an amine by a novel synthesis is described where a diol is monoalkylated with a chloromethyl resin followed by reaction with N,N'-carbonyldimidazole to afford a resin-bound tertiary-alkoxycarbonyl-imidazole which is subsequently N-alkylated and then sequentially treated with appropriate building blocks and reagents to afford a resin-bound amine which affords the desired amine after treatment with an acid as well as other valuable intermediates used in the process.
    Type: Grant
    Filed: October 7, 1998
    Date of Patent: August 3, 1999
