The tricyclic antipsychotic and antidepressant drug opipramol (opipramole) was examined with regard to the chemical structure of its organic impurities. Impurities were isolated from the technical product by chromatographic methods and their chemical structures were established by 1H NMR, MS and FTIR and further confirmed by comparison with commercially available products or with products obtained by independent synthesis, and in one case additionally by X-ray structure analysis.
对三环抗精神病和抗抑郁药物奥匹哌醇(opipramole)的有机杂质的化学结构进行了研究。通过色谱法从技术产品中分离出了杂质,并通过 1H-核磁共振、质谱和傅立叶变换红外光谱确定了它们的化学结构,还通过与市售产品或通过独立合成获得的产品进行比较,以及在一种情况下通过 X 射线结构分析进一步确认了它们的化学结构。
Phase transfer catalysis in<i>N</i>-alkylations of the pharmaceutical intermediates 5<i>H</i>-dibenz[<i>b,f</i>]azepine and 5<i>H</i>-10,11-dihydrodibenz[<i>b,f</i>]azepine
The two title compounds were alkylated under very mild phase-transfer-catalysis conditions. Differences in reactivities of the two heterocyclic nucleophiles, and in the reactivities of various alkyl halides are discussed.
