Abstract:
The present invention relates to processes for preparing enantiomerically pure cyclopropyl amine derivatives and salts thereof; the chiral intermediates such as the chiral salts are useful for the preparation of such chiral compounds and salts; pharmaceutical compositions comprising the compounds and salts; and method of using such compositions. The chiral cyclopropyl amine derivatives are useful for binding to histamine H3 receptor sites and for providing therapeutic agents for histamine H3 mediated disease.
Abstract:
The present invention relates to processes for preparing amine substituted benzofurans, and more particularly 4-(2-{2-[(2R)-2-methyl-1-pyrrolidinyl]ethyl}-1-benzofuran-5-yl)benzonitrile, and salts thereof. Compounds prepared by the processes of the invention have demonstrated activity as histamine-3 receptor ligands.
Abstract:
The present invention relates to the use of compounds of Formula (I) for the treatment of epilepsy, bipolar disorder, psychiatric disorders, migraine, pain, or movement disorders, and to provide neuroprotection.
Abstract:
A process of preparing 6-O-alkylerythromycin A using 9-oximesilyl erythromycin A derivatives is provided. 9-Oximesilyl- and 6-O-alkylerythromycin A derivatives used in the preparation of 6-O-alkylerythromycin A are also provided.
Abstract:
A process for the preparation of compounds of formula (I) or a salt thereof wherein X 1 , X 2 , X 3 , X 4 , R x , u, R 2, R 1g , z, and A 1 are as defined in the specification is disclosed.
Abstract:
The invention relates to a process according to scheme for preparing 2-methylpyrrolidine and, more particularly, specific enantiomers of 2-methylpyrrolidine. The corresponding 2-Iodomethylderivatives intermediates also are described. Scheme 1 (I)
Abstract:
Compounds of formula (I) are useful in treating conditions or disorders prevented by or ameliorated by histamine-3 receptor ligands. Also disclosed are pharmaceutical compositions comprising the histamine-3 receptor ligands, methods for using such compounds and compositions, and a process for preparing compounds within the scope of formula (I).
Abstract:
The present invention relates to an efficient process for the preparation of 5-(substituted)-10-methoxy-2,2,4-trimethyl-2,5-dihydro-1H-chromeno[3,4-f]quinolines.
Abstract:
A process for preparing a compound of structure (I), where A is oxygen and sulfur and R is selected from the group consisting of hydrogen, halogen, alkyl of one to six carbon atoms, alkoxy of one to six carbon atoms, and trifluoromethyl, and R is alkyl of one to four carbon atoms, comprising coupling a compound of formula (II), where X is bromine or iodine, with an N-hydroxyurea compound of formula (III), in the presence of a palladium catalyst. The compounds of formula (I) are inhibitors of the enzyme 5-lipoxygenase and are thus useful as therapeutic agents for the treatment of allergic and inflammatory disease conditions.
