Hydrochloride 2,3,3a,4,5,6-hexahydro-8-cyclohexyl-1H-pyrazino (3,2,1-j,k)carbazol has formula (I). A method of obtaining the claimed composition consists in that 6-cyclohexyl-3,4-dihydrocarbazol-1(2H) is alkylated by hydrochloride β-(N,N-dibenzylamino) ethylchloride in a two-phase system: an aromatic hydrocarbon-34-40 %-aqueous solution of alkali in the presence of an interphase transfer catalyst at a temperature of 85-110 °C with subsequent hydrogenation of the resulting 6-cyclohexyl-9β-(N,N-dibenzylamino) ethyl-3,4-dihydrocarbazol-1(2H) over palladium catalyst on a carrier in the medium of a higher aliphatic alcohol at a temperature of 50-70 °C and under a pressure of 1 to 30 atm with subsequent transfer of the obtained 2,3,3a,4,5,6-hexahydro-8-cyclohexyl-1H-pyrazino (3,2,1-j,k)carbazol into hydrochloride and extraction of the latter. The claimed composition has an antidepressive action and is an active substance of a pharmaceutical preparation with antidepressive action.
盐酸2,3,3a,4,5,6-六氢-8-环己基-1H-吡唑(3,2,1-j,k)咔唑的化学式为(I)。获得所述化合物的方法包括以下步骤:在芳香烃-34-40%碱性水溶液的两相体系中,加入相转移催化剂,将6-环己基-3,4-二氢咔唑-1(2H)与盐酸β-(N,N-二苯基氨基)乙基氯乙烷烷基化,反应温度为85-110°C,然后在高级脂肪醇介质中,于50-70°C、1-30大气压下,将所得的6-环己基-9β-(N,N-二苯基氨基)乙基-3,4-二氢咔唑-1(2H)在钯催化剂载体上进行氢化,随后将得到的2,3,3a,4,5,6-六氢-8-环己基-1H-吡唑(3,2,1-j,k)咔唑转化为盐酸盐并提取。所述化合物具有抗抑郁作用,是一种抗抑郁药物的活性成分。
