摘要:
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.
