Abstract
本发明涉及制备6-[3-(1-金刚烷基)-4-甲氧基苯基]-2-萘甲酸的新方法。
Description
本发明涉及制备一种在尤其用于治疗某些类型痤疮的药物组合物中使用的类视色素局部抗痤疮剂的式(I)的6-[3-(1-金刚烷基)-4-甲氧基苯基]-2-萘甲酸的新方法。
专利EP 0 199 636专门记载了式(I)的化合物。专利EP 0 199 636中记载了根据下列路线1制备该化合物:
路线1
在该方法中,第一步(a)中,将2-(1-金刚烷基)-4-溴苯甲醚转化成其有机镁化合物,之后通过氯化锌(ZnCl2)作用转化为其有机锌化合物,然后与6-溴萘甲酸甲酯进行偶合。该反应由过渡金属(钯或镍)或其与多种膦的络合物之一催化。因此,如专利EP 0 199 636(路线1)中所述,式(I)的6-[3-(1-金刚烷基)-4-甲氧基苯基]-2-萘甲酸是自2-金刚烷基-4-溴苯甲醚经过三步反应以63%的收率合成。
该反应的缺点之一为产生杂质。杂质之一是由“原位”产生的有机锌化合物与2-金刚烷基-4-溴苯甲醚反应生成的具有下列结构的3,3′-二(1-金刚烷基)-4,4′-二甲氧基-1,1′-联苯:
另一杂质还通过2-(1-金刚烷基)-4-溴苯甲醚的锌化合物转移到6-溴萘甲酸甲酯以及这种新锌化合物与6-溴萘甲酸甲酯反应得到具有下列结构的二聚体产物所产生:
该产物在皂化(步骤(b))以及酸化(步骤(c))后产生了下列杂质:
第三种杂质在反应介质的水解过程中生成。实际上,在该水解过程中,未反应的2-(1-金刚烷基)-4-溴苯甲醚的有机锌化合物产生具有下列结构的杂质:
在工业阶段中,这些杂质难以从终产物中除去而经常需要通过重结晶来进行后处理。
此外,一些催化剂如氯化[1,2-双(二苯基膦基)乙烷]合镍(NiCl2(dppe))必须单独制备,增加了该方法的步骤。
在步骤(a)的偶合反应中,酸官能团以甲酯的形式进行保护。该酸官能团应重新生成。因此,在第二步(b)中,将6-[3-(1-金刚烷基)-4-甲氧基苯基]-2-萘甲酸甲酯在醇如甲醇中在回流状态下用碱如氢氧化钠(NaOH)或氢氧化钾(KOH)处理进行皂化。
在第三步(c)中,用盐酸酸化反应介质得到6-[3-(1-金刚烷基)-4-甲氧基苯基]-2-萘甲酸。应注意在该方法中,6-溴萘甲酸的甲酯应该由相应的酸一步制备而成。因此,可以发现现有技术方法复杂而不能完全令人满意。
在上下文中,本发明的目的之一是提供一种更简便、更经济的制备6-[3-(1-金刚烷基)-4-甲氧基苯基]-2-萘甲酸的方法。本发明的方法更适于工业生产,尤其是就成本而言,并且符合良好生产规范(GoodManufacturing Practices)。本发明的目的之一为提供制备化合物(I)的新方法,所述方法不需要酸官能团的最后阶段脱保护、避免产生上述杂质并且可减少合成步骤数目。
在上下文中,本发明的主题为制备式(I)的6-[3-(1-金刚烷基)-4-甲氧基苯基]-2-萘甲酸的方法:
该方法由式(II)的3-金刚烷基-4-甲氧基苯基硼酸与式(III)的6-溴-2-萘甲酸进行一步Suzuki反应来进行:
本发明的主题一方面还是使用化合物(II),而另一方面是使用化合物(III)来制备式(I)的化合物的用途。
因此,根据本发明的方法,可一步将6-[3-(1-金刚烷基)-4-甲氧基苯基]-2-萘甲酸的(1-金刚烷基)苯基部分和萘基部分进行偶合。
根据本发明的方法,6-[3-(1-金刚烷基)-4-甲氧基苯基]-2-萘甲酸的制备在下列路线2中描述:
路线2
6-[3-(1-金刚烷基)-4-甲氧基苯基]-2-萘甲酸(I)是由3-金刚烷基-4-甲氧基苯基硼酸(II)(具体按照与专利申请WO 02/072009 A2和WO03/011808 A1中记载的类似方法进行制备)和市售的6-溴-2-萘甲酸(III)进行Suzuki反应来制备。路线2的新方法所述的式(I)的6-[3-(1-金刚烷基)-4-甲氧基苯基]-2-萘甲酸的制备是由2-(1-金刚烷基)-4-溴苯甲醚(IV)(如按照EP 0 199 636制备)经两步反应进行,其收率大大高于现有技术方法得到的收率。如下述实例所示,本发明方法的收率可为大约95%或更高。
在本发明的上下文中,Suzuki反应是通过在极性溶剂中,钯催化剂和碱存在下,使化合物(II)和化合物(III)发生偶合,接着用酸处理来进行。
通常,Suzuki反应可以在钯催化剂如醋酸钯(II)、四(三苯基膦)合钯(0)、钯/活性炭或二氯[1,1′-双(二苯基膦基)二茂铁]合钯(II)的存在下,在非质子极性溶剂(如乙腈、N,N-二甲基甲酰胺、二甲氧基乙烷或四氢呋喃)或质子极性溶剂(如正丙醇、异丙醇)或这些溶剂与水的混合物中进行。所用溶剂的体积为6-溴-2-萘甲酸(III)使用量的7-13倍,所用水的体积为6-溴-2-萘甲酸(III)使用量的7-13倍。
钯催化剂可以有利地含有选自以下的配体:三苯基膦、三邻甲苯基膦、三间甲苯基膦或三对甲苯基膦。特别优选的催化剂为醋酸钯(II)和钯碳,其可得到特别快的反应动力学。醋酸钯(II)可以有利地与2-(二环己基膦基)联苯型配体联合使用(J.P.Wolfe等,J.Am.Chem.Soc.,1999,121,9550-9561)。
这些催化剂也可被包囊,例如Pd EnCatTM型催化剂。该反应通常是在无机碱如碳酸钾、碳酸钠、碳酸铯、氢氧化钠或氢氧化钾存在下或在叔胺如三乙胺或二异丙基乙基胺的存在下进行。特别优选的碱为碳酸钾、氢氧化钾以及二异丙基乙基胺。
Suzuki反应优选在惰性气氛,如氩气或氮气气氛下进行。反应混合物有利地在60至110℃温度加热30分钟至24小时。在酸性介质如HCl存在下进行处理。应注意,根据在实施例1和2中使用的条件,该反应动力学很快并在两小时内完成。本领域的技术人员将可以改变这些条件,特别是通过应用在文献(N.Miyaura&A.Suzuki,Chem.Rev.,1995,95,2457-2483;A.Suzuki,J.Organomet.Chem.,1999,576,147-168)中记载的Suzuki反应变量来改变。因此,本发明的方法简便、经济并且可以高收率、几乎定量地直接得到化合物(I)。
该新方法还可得到高纯度的6-[3-(1-金刚烷基)-4-甲氧基苯基]-2-萘甲酸,其中完全不存在现有技术方法中出现的杂质。下列制备方法阐述了本发明的方法。
