制备方法与用途

合成方法

2,2-二甲基哌嗪的一种制备方法如下：

首先，将3,3-二甲基哌嗪-2-酮（8.28 kg，64.6 mol）与四氢呋喃（THF）（60 kg）的混合物加热至50-60℃。在氮气保护下，搅拌THF（50 kg），并分批加入氢化铝锂。待气体演化停止后，继续加入更多的氢化铝锂。随后，在41-59℃下，3,3-二甲基哌嗪-2-酮溶液缓慢滴加至混合物中，历时约2小时。搅拌均匀后，保持悬浮液在59℃（夹套温度60℃）下再搅拌一小时。

将反应混合物冷却，在2小时内分批加入水，确保温度维持在25°C以下。

随后，在23°C下滴加15%的氢氧化钠溶液（3.50 kg），持续搅拌20分钟，并需保持冷却。再加入更多的水并在氮气保护下搅拌过夜。

完成上述步骤后，过滤混合物，滤饼用THF（40 kg）洗涤。合并滤液并进行浓缩处理，直至反应器温度达到70℃（蒸馏温度为66℃）。最后，在旋转蒸发器上进一步浓缩剩余物，并在常压下进行分馏。最终在163℃收集得到2,2-二甲基哌嗪。

  Enhanced D1 Affinity in a Series of Piperazine Ring Substituted 1-Piperazino-3-Arylindans with Potential Atypical Antipsychotic Activity

  摘要：

  A study of the effect of aromatic substitution on D-1 and D-2 affinity in a series of previously reported trans-1-piperazino-3-phenylindans shows similar structure-activity relationships for the two receptor sites. 6-Substituted derivatives have affinity for both receptors, and 6-chloro- or B-fluoro-substituted derivatives show preference for D-1 receptors. D-1 affinity and selectivity are significantly increased in a series of new piperazine ring substituted derivatives. Potent D-1 and D-2 antagonism in vivo are confined to derivatives with relatively small substituents in the 2-position of the piperazine ring (e.g. 2-methyl, 2,2-dimethyl, 2-spirocyclobutyl or 2-spirocyclopentyl). Consequently, the effect of aromatic substitution is examined in a series of 1-(2,2-dimethylpiperazino)-3-arylindans. All these compounds except the 4-, 5-, 7- and 4'-chlorosubstituted derivatives have potent D-1 affinity (IC50's below 10 nM) and the majority of the compounds antagonize SK&F 38393-induced circling in 6-OHDA-lesioned rats with ED(50) values about 1 mu mol/kg. In vitro all compounds show preference for D-1 receptors, but in vivo they are equally effective as D-1 and D-2 antagonists. The compounds have high affinity for 5-HT2 receptors and selected compounds show high affinity for alpha(1) adrenoceptors. Furthermore, a subgroup consisting of (-)-38, (-)-39, (-)-41, and (-)-54 does not induce catalepsy in rats. These compounds have the potential of being ''atypical'' antipsychotics and have consequently been selected for further studies. The non-receptor-blocking enantiomers are shown to be inhibitors of DA and NE uptake in accordance with previous observations in compounds unsubstituted in the piperazine ring. Two compounds, (+)-38 and (+)-40, block DA uptake with IC50 values below 10 nM. Finally, the observed structure-activity relationships are discussed in relation to previously published pharmacophore models for D-2 and 5-HT2 receptors. It is concluded that the piperazine substituents might induce a different binding mode at the dopamine receptor sites, perhaps only at the D-1 receptor site.
