  Process to prepare dihydropyridine and derivatives thereof

  摘要：

  本发明揭示了一种制备二氢吡啶化合物及其衍生物，尤其是费洛地平的新工艺。制备费洛地平的过程包括两步反应，将2,3-二氯苯甲醛与乙酰乙酸甲酯在催化剂体系存在下缩合反应。所得的苯亚甲基中间体随后与乙基氨基巴豆酸酯顺序反应，得到费洛地平。本发明的新颖性部分在于：（1）一种先前未披露的新催化剂体系用于制备费洛地平，（2）缺少酸的存在，（3）控制反应条件以产生与已知反应相比更少的未反应醛，（4）简化的纯化过程，（5）形成可忽略数量的对称二酯副产物。

  4-Substituted-1,4-dihydropyridines are prepared by a cycloaddition reaction in which the cyclization is driven to completion, after thermal reaction, by addition of an acid. Felodipine, a vasodilator, is prepared by a cycloaddition reaction of ethyl 3-aminocrotonate with a suitably substituted dichlorobenzylidine under reaction conditions whereby the product crystallizes out of the reaction solution and may be directly isolated by filtration.

  4-取代的-1,4-二氢吡啶是通过环化反应制备的，在该反应中，在热反应之后，通过加入一种酸使环化完成。非洛地平是一种血管扩张剂，它是通过 3-氨基巴豆酸乙酯与适当取代的二氯苄啶在反应条件下发生环化反应制备的，反应产物从反应溶液中结晶出来，可直接通过过滤分离。

  [Problem] To provide a compound which may be used in treating diseases in which a calcium sensing receptor (CaSR) is concerned, particularly hyperparathyroidism. [Means for Resolution] It was found that novel pyrrolidine derivatives which are characterized by the possession of aminomethyl group substituted with arylalkyl group or the like, or salts thereof, have excellent CaSR agonistic regulatory activity and also have excellent selectivity with CYP2D6 inhibitory activity having a possibility of causing drug interaction. Based on the above, these novel pyrrolidine derivatives are useful as therapeutic agents for treating diseases in which CaSR is concerned (hyperparathyroidism, renal osteodystrophy, hypercalcemia and the like).

  [问题]提供一种可用于治疗钙传感受体（CaSR）相关疾病，特别是甲状旁腺机能亢进症的化合物。 [解决方法] 研究发现，新型吡咯烷衍生物（其特征在于具有被芳基烷基或类似基团取代的氨甲基）或其盐具有优异的 CaSR 激动调节活性，同时还具有优异的选择性和 CYP2D6 抑制活性，但有可能引起药物相互作用。基于以上所述，这些新型吡咯烷衍生物可作为治疗剂用于治疗与 CaSR 有关的疾病（甲状旁腺机能亢进症、肾性骨营养不良症、高钙血症等）。
