摘要:
A process for reducing the content of ethyl 3-dimethylamino-2-phenylpropionate in a solution, contaminated therewith, of ethyl 2-dimethylamino-1-phenyl-3-cyclohexene-1-carboxylate in a water-immiscible solvent, which comprises adding from 0.5 to 2.0 equivalents of a carboxylic acid per mole of ethyl 2-dimethylamino-1-phenyl-3-cyclohexene-1-carboxylate to this solution, and stirring this mixture at a temperature of from 50° C. to 100° C., is described.
摘要:
The fumaric acid salt of 2-{3-[4-(2-t-butyl-6-trifluoromethyl-4-pyrimidinyl)-1-piperazinyl]propylthio}-4-pyrimidinol is useful for treating disorders which respond to dopamine D3 ligands. It has higher stability at low pH and is therefore particularly suitable for oral administration in pharmaceutical compositions comprising this salt.

摘要:
5H-Dibenzo[a,d]cyclohepten-5-ones (I) ##STR1## (A and B being radicals for completing aromatic ring systems) are prepared by converting (Z)-2-(2-arylethenyl)arylcarboxylic acids (II) ##STR2## or E/Z-isomer mixtures thereof with a halogenating agent for carboxylic acids at from (-30.degree.) to +120.degree. C. to the corresponding carbonyl halides (III) ##STR3## where X is halogen, and cyclizing said carbonyl halides at from 0.degree. to 100.degree. C. in the presence of a Lewis acid.
