Novel spiro-quaternary ammonium halides are disclosed. The new compounds are particularly valuable as intermediates in preparation of N-(2-pyrimidinyl)piperazinylalkyl derivatives of azaspiroalkanediones such as the psychopharmacologic agent 8-[4-[4-(2-pyrimidinyl)-1-piperazinyl]butyl]-8-azaspiro[4.5]decane-7,9-dio ne.
新的螺环季铵盐化合物已被披露。这些新化合物在制备N-(2-嘧啶基)哌嗪烷基衍生物,如具有精神药理作用的化合物8-[4-[4-(2-嘧啶基)-1-哌嗪基]丁基]-8-氮杂螺[4.5]癸烷-7,9-二酮中作为中间体时具有特别的价值。
