55105220, Apr 23, 1996
Filed:
Feb 22, 1995
Appl. No.:
8/393428
Inventors:
Jorge R. Barrio - Agoura Hills CA
Allyson J. Bishop - Wahnemuhle, DE
Mohammad Namavari - Los Angeles CA
Gerald T. Bida - Shreveport LA
Assignee:
Regents of the University of California - Oakland CA
International Classification:
C07C22900
US Classification:
562446
Abstract:
A process for forming a 6-fluoro derivative of compounds in the L-Dopa family comprising the steps of protecting the groups attached to the benzene ring in the compound followed by serially reacting the protected compound with (a) iodine and silver trifluoroacetic acid; (b) Bb. sub. 3 ; (c) dit-butyldicarbonate; (d) hexamethyltin; (e) a fluoro compound; (f) hydrobromic acid; and (g) raising the pH to. ltoreq. 7.

Device And Process For The Production Of Nitrogen-13 Ammonium Ions Using A High Pressure Target Containing A Dilute Solution Of Ethanol In Water

US Patent:
53454774, Sep 6, 1994
Filed:
Jun 19, 1991
Appl. No.:
7/717268
Inventors:
Bruce W. Wieland - El Cerrito CA
Gerald T. Bida - Rodeo CA
George O. Hendry - Napa CA
Henry C. Padgett - Walnut Creek CA
Assignee:
CTI Cyclotron Systems, Inc. - Knoxville TN
International Classification:
G21G 110
US Classification:
376195
Abstract:
A system and process for the production of nitrogen-13 ammonium ions from a target material in the form of a dilute solution of ethanol in natural water by the reaction of protons with oxygen-16 within the target material. The system includes a device for producing a proton beam which travels along a preselected path and strikes the target material in a target chamber. This target chamber is positioned in the path of the proton beam such that subjection of the target material to the beam produces nitrogen-13 atoms in a predetermined form. These nitrogen-13 atoms are converted in the aqueous solution to ammonium, ions and oxides and are conducted from the target holder to a purification device for collecting a purified product containing such ammonium ions. A cooling system serves to dissipate heat generated during the production of the nitrogen-13 atoms by the reaction of protons with the oxygen. Other solutes for the target material are discussed.
