Abstract: A process for preparing (S,S)-cis-2-benzhydryl-3-benzylaminoquinuclidine. The process includes the steps of contacting a compound containing a mixture of R- and S-isomers and having the formula with an effective amount of a chiral organic acid in the presence of an organic solvent and an effective amount of an organic carboxylic acid for converting the R-isomer into an acid salt of the S isomer, wherein the organic solvent is capable of solubilizing the compound containing the mixture of R- and S-isomers, while precipitating the acid salt and the organic carboxylic acid is different from the chiral organic acid; neutralizing the acid salt with a base to provide an S-isomer of a chiral ketone of the formula ; and reacting the chiral ketone with an organic amine in the presence of a Lewis acid to provide the corresponding imine and reducing the imine.
Abstract: This invention relates to a powder for oral suspension, and an oral suspension made therefrom, which comprises a n-propanol solvate of non-dihydrate azithromycin and an azithromycin conversion stabilizing excipient, wherein said excipient reduces the conversion of the form of azithromycin, when placed in suspension, to another form of azithromycin. This invention also relates to an oral suspension which comprises a n-propanol solvate of non-dihydrate azithromycin and an aqueous vehicle.
Abstract: This invention relates to cycloalkylpyrrole-3-carboxylic acid derivatives and heterocycloalkylpyrrole-3-carboxylic acid derivatives that bind with high selectively and/or high affinity to the benzodiazepine site of GABAA receptors. This invention also relates to pharmaceutical compositions comprising such compounds and to the use of such compounds in the treatment of central nervous system (CNS) diseases. This invention also relates to the use of these cycloalkylpyrrole-3-carboxylic acid derivatives and heterocycloalkylpyrrole-3-carboxylic acid derivatives in combination with one or more other CNS agents to potentiate the effects of the other CNS agents. Additionally this invention relates to the use such compounds as probes for the detection of GABAA receptors in tissue samples.
