Chloracylamido derivatives IIIa-Va were obtained by acylation of 4-amino-s-hydrindacene with chloroacetyl chloride, 2-chloropropionyl chloride and 3-chloropropionyl chloride; their reactions with excessive diethylamine, pyrrolidine, piperidine and morpholine afforded the title compounds IIIbcde-Vbcde. A reaction of 4-amino-s-hydrindacene with benzoyl isothiocyanate gave 1-benzoyl-3-(s-hydrindacen-4-yl)thiourea (VI) whose mild alkaline hydrolysis resulted in N-(s-hydrindacen-4-yl)thiourea (VII). The following treatment with methyl iodide and then with ethylenediamine afforded the imidazoline derivative VIII in a low yield. N-(s-Hydrindacen-4-yl)-2-piperidinoacetamide (IIId) in the form of the hydrochloride revealed a high degree of local anaesthetic and antiarrhythmic activity.
通过使用氯乙酰氯、2-氯丙酰氯和3-氯丙酰氯对4-氨基-s-氢吲哚啉进行酰化反应,得到了Chloracylamido衍生物IIIa-Va;它们与过量的二乙胺、吡咯烷、哌啶和吗啡啉反应,形成了标题化合物IIIbcde-Vbcde。4-氨基-s-氢吲哚啉与苯甲酰异硫氰酸酯反应,得到1-苯甲酰-3-(s-氢吲哚啉-4-基)硫脲(VI),其轻微碱性水解产生N-(s-氢吲哚啉-4-基)硫脲(VII)。随后,使用甲基碘和乙二胺进行处理,得到了低收率的咪唑啉衍生物VIII。以盐酸形式出现的N-(s-氢吲哚啉-4-基)-2-哌啶乙酰胺(IIId)具有高度的局部麻醉和抗心律失常活性。
