  • Patent number: 6057371
    Abstract: The invention relates to methods for the treatment of central nervous system disorders, gastrointestinal disorders, drug abuse, angina, migraine, hypertension and depression by administering a pharmaceutical composition comprising an effective amount of certain sigma receptor ligands to a patient in need of such treatment. The invention further relates to novel sigma receptor ligands having high binding to the sigma receptor and pharmaceutical compositions thereof. Unexpectedly, certain of the sigma receptor ligands of the present invention have selectivity for the sigma receptor over the DA, PCP and 5-HT.sub.1A receptors.

  • Patent number: 6028224
    Abstract: A synthesis of fluoxetine is disclosed. The process begins with a lower alkyl ester of 3-benzoylpropionic acid, which is reduced in the presence of a chiral ligand to produce the corresponding .gamma.-hydroxy ester, and the ester is cleaved. The free acid is then condensed with the alcohol to form a .gamma.-lactone, which is treated with ammonia to provide the .gamma.-hydroxy amide. The amide undergoes a Hoffman rearrangement to provide a 2-oxo-1,3 oxazine, which is reduced to 3-(methylamino)-1-phenyl-1-propanol. The alcohol is deprotonated and reacted with a 4-chloro- or 4-fluoro benzotrifluoride to provide fluoxetine free base.

  • Patent number: 6018079
    Abstract: A simple and inexpensive process is described for reducing the concentration of N-nitroso-containing compounds in compositions comprising N-nitroso-containing compounds and other desired compounds wherein the N-nitroso-containing compounds thermally decompose at a temperature below the decomposition temperature of the desired compounds. For compositions comprising dinitroaniline herbicides wherein the N-nitroso compound is a N-nitroso derivative of a precursor in the manufacture of the herbicide, for example Flumetralin, N-ethyl-N-(2-chloro-6-fluorobenzyl)-2,6-dinitro-4-trifluoromethylaniline, the process requires heating the mixture to a temperature greater than about 120.degree. C., and holding the composition at that temperature for a time effective to decompose the N-nitroso compound present in the mixture. Volatile decomposition products are advantageously removed from the composition.
