Patent number: 8642761Abstract: The present invention describes a method for the synthesis of enantiomerically pure 3-amidinophenylalanine derivatives, which are used as pharmaceutically effective urokinase inhibitors, by starting from 3-cyanophenylalanine derivatives. The methods of manufacture comprising only one synthesis step lead to new intermediates, namely 3-hydroxyamidino- and 3-amidrazonophenylalanine derivatives. These intermediates or their acetyl derivatives can be reduced into the desired 3-amidino-phenylalanine derivatives under gentle conditions (H2 or ammonium formiate, Pd/C (approx. 10%), ethanol/water, room temperature, normal pressure or also H2, Pd/C, AcOH or HCl/ethanol, 1-3 bar) in excellent yields and in an enantiomeric excess of up to 99.9%.Type: GrantFiled: November 18, 2011Date of Patent: February 4, 2014Assignee: Wilex AGInventors: Hugo Ziegler, Peter Wikstroem
