Description
技术领域
本发明涉及制备决奈达隆及其药学上可接受的盐的新颖方法,在这种方法中使用的新颖中间体化合物和它们的制备。
背景技术
决奈达隆是用于治疗心律失常的已知药物,并具有化学名称N-[2-正丁基-3-[4-[3-(二-正丁基氨基)丙氧基]苯甲酰基]苯并呋喃-5-基]甲磺酰胺[也参见下式(I)]。存在一些制备决奈达隆的已知方法,如下所示:
在EP0471609中,披露了用于制备决奈达隆的以下方案[方法A]
上述专利说明书也披露了一些新的中间体化合物。
在WO02/48078中,披露了用于制备决奈达隆的以下方案[方法B]:
所述方法的新颖性基于在第一步中的弗瑞德-克来福特反应(Friedel-Crafts reaction)的调整。在此文献中也披露了用于制备第一步的苯甲酰氯化合物的方法和中间体化合物。所述方法的其它步骤与EP0471609中披露的合成路线[方法A]的最后步骤相同,但是在权利要求中,要求保护整个合成路线,直至决奈达隆。
在WO02/48132(Sanofi)中,披露了以下反应路线[方法C]。这种方法是所谓的超收敛路线(superconvergent route)。在此路线的第一步中,将5-氨基-2-丁基-苯并呋喃
在这种方法中,反应步骤的顺序被改变,还原和甲磺酰化步骤在操作开始时实施。除了用于制备决奈达隆的反应路线之外,也要求保护起始物质2-丁基-5-甲磺酰氨基-苯并呋喃和它的制备。
在所述操作中,第一个[方法A]是所谓的线性合成。以此操作方式,决奈达隆的不同部分在起始化合物上逐步构建。这种方法是最不经济的,因为进行化学基团的逐步构建,其中使用越来越复杂和昂贵的分子,其提高制备成本。而且,它包含复杂和危险的反应步骤,因为在甲氧基的断裂反应中使用氯化铝,其使得工业可行性更加复杂。
在WO02/48078(方法B)中,披露了较短的合成路线,其使得这种方法更经济,但是它的最后反应步骤保留了氨基的甲磺酰化反应。这种反应步骤(参见在WO02/48078的实施例6中描述的方法)是复杂的并得到低收率,仅61.6%。纯产物可在使用色谱柱纯化的纯化后得到,这种方法是必需的,因为二甲磺酰化产物的分离困难。
考虑到反应步骤的数目,在WO02/48132(方法C)中披露的方法较简单和更经济。不幸的是,在最后的反应步骤中,形成相当不纯的决奈达隆.HCl(盐酸盐),其明显是在弗瑞德-克来福特反应中存在二丁基氨基的结果。根据实施例3和4,以90%的收率制备粗决奈达隆盐酸盐,将其进一步纯化并最终以86%收率得到粗决奈达隆碱。使这种碱与溶解在异丙醇中的氯化氢气体反应,其得到纯决奈达隆盐酸盐。未给出该反应步骤的收率。根据实施例5,粗决奈达隆盐酸盐以90%的收率制备,使其用水洗涤并与溶解在异丙醇中的氯化氢气体反应,再次得到决奈达隆盐酸盐。该产物的质量未知。然而,在弗瑞德-克来福特反应中使用的组分和所得产物和副产物均不溶于水,除了除去无机盐之外,用水洗涤的步骤不能得到任何纯化。
这种方法还有另一个缺点,即,在5-氨基-2-丁基-苯并呋喃的甲磺酰化反应中形成二甲磺酰化副产物。纯化通过结晶进行,其具有78.5%的收率。
本发明的一个目的是提供制备式(I)的决奈达隆的新颖方法,所述方法起始于已知和可商购物质,使用简单和环境可相容试剂和溶剂,并得到高的总收率和良好的产物纯度。
发明内容
本发明的主要方面是制备决奈达隆(I)及其药学上可接受的盐的方法,
其包括使式(II)化合物或者其盐与式L-(CH2)3-CH3(III)化合物(其中L为离去基团)反应,作为碱分离所得产物,并且如果希望的话,将它转化成其药学上可接受的盐,
所述式(II)为:
本发明避免了前述操作的缺点,因为在最后步骤中决奈达隆的形成用丁醇衍生物(例如丁醇的有机和无机酯)完成。发明人意料不到地发现,式(III)化合物可与式(II)化合物的氨基以这样的方式连接,即,其中连接仅在游离氨基[见式(II)的“右”侧]上发生,而不在磺酰氨基[见式(II)的“左”侧]上发生。
式(III)化合物可商购或者可通过已知方法制备(J.of Steroid Biochemistryand Molecular Biology80,(2002),429-440;Synthesis(1979,882)。根据EP0471609,式(III)的起始物质也是已知的,以及根据WO02/48132,式(X)化合物也是已知的。

在所述方法中,应使用甲磺酰化试剂。它可为可用于将CH3SO2–基团插入式(VI)化合物的游离氨基中的任何试剂。实用的是使用甲磺酸酐或者甲磺酰基卤化物,例如甲磺酰氯。
E)为了制备式(II)化合物
将上面的式(IV)化合物氢化。
反应在常用氢化条件中进行。例如,氢化方法在溶剂中在催化剂的存在下进行,所述催化剂例如Ni催化剂,其通常为兰尼镍(Raney-Ni)。通常,溶剂选自C1-4醇、乙酸乙酯和环己烷,例如溶剂为甲醇或者乙醇。
E’)可选择地,式(II)化合物可由另一起始物质制备,即,通过任何已知方法脱保护式(V)化合物
其中Pg为氨基保护基团。
Pg氨基保护基团通常为A-CO-基团,其中A为烷基、烷氧基、芳基或者芳基氧基,例如其为乙氧基羰基。

F)最后,为了制备式(I)的决奈达隆及其药学上可接受的盐,
使上面的式(II)化合物或者其盐与式L-(CH2)3-CH3(III)化合物(其中L为离去基团)反应,然后将所得产物作为碱分离,并且如果希望的话,将它转化成其药学上可接受的盐。
通常,L的定义选自卤素、甲磺酰基氧基、三氟甲磺酰基氧基和苯磺酰基氧基,其任选取代有卤素、烷基、烷氧基、硝基或者经保护的氨基。
在另一实施方案中,反应步骤F在溶剂(或者溶剂混合物)中,任选在碱和/或催化剂的存在下进行。在另一实施方案中,反应在溶剂中进行并使用碱和催化剂。
上面的溶剂通常选自酮、醇、酯、酰胺、醚、二甲亚砜和芳族溶剂及其任何混合物。在一个具体实施方案中,溶剂为酮,例如丙酮或者甲基乙基酮。在另一实施方案中,溶剂为醇,例如甲醇、乙醇、异丙醇或者正丁醇。

在反应中使用的温度通常在0℃和溶剂(其可为溶剂混合物,如上所述)的沸点之间,例如60-120℃。通常,在反应期间施加大气压力。
为了制备药学上可接受的盐,可使用的酸可为与通式(I)的化合物形成酸加成盐的任何无机或者有机酸。可形成酸加成盐的示例性酸如下:乙酸、己二酸、海藻酸、抗坏血酸、天冬氨酸、苯甲酸、苯磺酸、甲磺酸、乙磺酸、硼酸、丁酸、柠檬酸、富马酸、氢氯酸、氢溴酸、氢碘酸、2-羟基乙烷磺酸、马来酸、草酸、硝酸、水杨酸、酒石酸、硫酸(形成硫酸根或者硫酸氢根阴离子)、磺酸(例如本申请所述的那些)、琥珀酸、甲苯磺酸等。卤化氢盐是常用的,尤其是氢氯酸盐。
这里提及,在通式(I)化合物的甲磺酰基(参见分子的“左侧”)上,可通过强碱,例如碱金属氢氧化物,通常通过氢氧化钠形成盐(在它的酰胺部分上)。然而,这些盐具有不太实用的重要性,但是它们在盐的范围内。这意味着,术语“盐”在通式(I)化合物的情况中包括酸加成盐和通过碱形成的盐(碱性盐)。
如上所述,其它起始物质可商购或者可通过使用已知合成方法制备,例如,如在相关实施例10–13中所述。

这里提及,上面的中间体化合物中的一些具有甲磺酰基(参见分子的“左侧”),其中可通过强碱,例如碱金属氢氧化物,通常通过氢氧化钠形成盐(在它的酰胺部分上)。然而,这些盐具有不太实用的重要性,但是它们在可通过权利要求保护的方法制备的盐的范围内,即,在这种情况中(其中分子具有甲磺酰基)术语“盐”包括由碱形成的盐(碱性盐)。
