Abstract
本发明揭示了式(I)代表的1,5-苯并硫氮杂䓬衍生物(见附图)的制备方法,它包括在式(III):R′SO<sub>3</sub>H(其中R1表示烷基或是取代或非取代苯基)磺酸化合物的存在下使式(II)的丙酸化合物进行分子内环化反应(R是低级烷基)。
Description
本申请是申请号为CN.90102552.6的专利申请的分案申请。
其中R表示低级烷基。
上述1,5-苯并硫氮杂
衍生物用作合成药物化合物,例如具有优良冠状血管舒张活性的(+)-顺-2-(4-甲氧苯基)-3-乙酰氧基-5-(β-二甲基氨乙基)-2,3-二氢-1,5-苯并硫氮杂
-4(5H)酮(普通名:硫氮
酮的中间产物是很有用的。
至此,1,5-苯并硫氮杂
衍生物(Ⅰ)的制备方法是人们至今所知道的方法,例如,该方法是在回流条件下二甲苯中使2-羟基-3-(2-氨基苯基硫代)-3-(4-甲氧基苯基)丙酸进行分子内闭环反应(日本专利公报第8038/1978号)。但是,该方法的缺陷在于为了反应完全需要很长的时间(上述公报的实例中需12小时)。
本发明者已进行了种种研究,结果他们发现,在特定磺酸化合物的存在下,使特定的丙酸化合物进行分子内闭环反应时,反应时间可明显缩短,化合物(Ⅰ)的收率良好。
即,根据本发明,在由式(Ⅲ)R′SO3H(其中R′表示低级烷基或取代或非取代苯基)的磺酸化合物存在下使式(Ⅱ)代表的丙酸衍生物进行分子内闭环反应制得式(Ⅰ)表示的所需化合物:
其中R的定义同上
用于本发明中分子内闭环反应的磺酸化合物(Ⅲ)的例子包括,例如,式(Ⅲ)化合物中R′是诸如甲基、乙基、丙基或丁基的具有1~4个碳原子烷基或者可被至少一个这些烷基所取代的苯基。在这些化合物中,较好的是甲磺酸和对-甲苯磺酸。所述的磺酸的用量无特定的限制,但一般说来较好地是用0.5~10W/W%的量,最好的是约1~6W/W%以化合物(Ⅱ)为基础。
上述反应较好地是在回流中在诸如二甲苯、甲苯等高沸点溶剂中进行。
通过一些简易的操作,例如,冷却反应混合物、通过过滤收集沉淀的晶体并用合适的溶剂(例如,乙醇、乙醇水溶液等)对它们进行洗涤可分离出不含磺酸化合物(Ⅲ)的所需化合物(Ⅰ)的纯产物。用已知的方法使这样得到的化合物(Ⅰ)转化成由式(Ⅳ)代表的相应的3-乙酰氧基-5-(β-二甲基氨乙基)-1,5-苯并硫氮杂
衍生物或其药学上可接受的盐:
(其中R的定义同上),在已知的方法中有:例如日本专利公报第18038/1978和43785/1971(已审查)和美国专利第3,562,257和4,438,035所述的方法,这里列出目录仅供参考。
根据上述本发明的方法,分子内闭环反应所需的时间明显缩短,并且可以高收率地得到所需化合物,且化合物的纯度很高。因此,本发明的方法作为工业生产相当优良。
在说明书和权利要求书中,术语“低级烷基”特指有1~4个碳原子的烷基。
实验实施例
使12.75克(+)-苏型-2-羟基-3-(2-氨基苯基硫代)3-(4-甲氧基苯基)丙酸在52毫升二甲苯或甲苯中加热回流并不断除去所形成的水来形成(+)-顺-2-(4-甲氧苯基)-3-羟基-2,3-二氢-1,5-苯并硫氮杂
-4(5H)-酮,检查反应系统中磺酸存在的作用。结果如表1和2所示。
在这些表中,磺酸的用量是以起始化合物为基础,对-甲苯磺酸则使用其单水合物。
