| titleOfInvention | Process for preparing acid addition salt of Z-isomer of triphenylethylene compound |
| abstract | The present invention provides a process for preparing an acid addition salt of the Z-isomer of a compound of the formula ##STR1## wherein R 1 and R 2 represent a lower alkyl group, or taken together with the nitrogen atom to which they are attached, form a nitrogen-containing heterocyclic group optionally containing other hetero atom or atoms; R 3 and R 4 represent H, a lower alkyl group, OH, a lower alkoxy group, a lower alkylcarbonyloxy group, an arylcarbonyloxy group optionally substituted with 1-2 substituents selected from lower alkyl, lower alkoxy, halo and CN on the benzene ring, a benzylcarbonyloxy group, a mono- or di(lower alkyl)aminocarbonyloxy group or a mono- or di(aryl)aminocarbonyloxy group; R 5 represents a lower alkyl group or halo; and n represents 1-6, characterized in that the E-isomer of the compound of the formula (I) or its acid addition salt, singly or in admixture with the Z-isomer or its acid addition salt, is heated in an organic solvent containing hydrobromic acid. |
