Process for the preparation of carbostyril derivatives |
| abstract |
A process for preparing carbostyril derivatives such as aripiprazole is described. Dichlorophenylpiperazine or an acid addition salt thereof is reacted with a compound of formula X-C4H8-Y or X-C4H6-Y to produce a novel quaternary spiro ammonium salt intermediate which is optionally isolated and purified. The quaternary spiro ammonium salt intermediate is reacted with 7-hydroxydihydrocarboxystyryl to produce the carbostyril derivative. |
