Abstract
通式(Ⅰ)的2－三氟甲氧基苯磺酰胺是生产除草活性化合物的中间体。本发明涉及以很高的产率和高纯度生产该化合物的方法,该方法包括将其中X1表示卤素,X2表示氢或卤素的通式(Ⅱ)的卤化三氟甲氧基苯磺酰胺在催化剂和稀释剂存在下与氢反应,适当的,在酸受体存在下和在0℃—200℃温度范围内反应(脱卤),当“X2=卤素”时,用常规的方法分离得到的式(Ⅰ)化合物,而当“X2=H”时,用质子极性有机液体处理而转化成纯的结晶产物,并通过抽滤除去液体组分而分离出产物。
Description
本发明涉及生产2-三氟甲氧基苯磺酰胺的新方法，该化合物是生产除草活性化合物的原料。
已知将2-三氟甲氧基苯磺酰氯与氨反应可得到2-三氟甲氧基苯磺酰胺(参见Zh.Org.Khim.，8(1972)，1023-1-26(俄文)a.k.a.J.Org.Chem.USSR，8(1972)，1032-1035(英文)，引用于Chem.Abstracts，77：61964；还可参见US 4732711。
虽然反应顺利进行而且以高产率和高质量生成2-三氟甲氧基苯磺酰胺，但要求用2-三氟甲氧基苯胺通过米尔文(Meerwein)反应预先制备作为原料的2-三氟甲氧基苯磺酰氯，而此反应在技术上相对来说是比较复杂的。而且作为其前体的2-三氟甲氧基苯胺，能够得到的数量也是有限的。
现在，发现可以下述方法以很高的产率和高纯度得到式(I)的2-三氟甲氧基苯磺酰胺：
该方法是将下述通式(II)的卤化三氟甲氧基苯磺酰胺其中
X1表示卤素，和
X2表示氢或卤素，在催化剂和稀释剂存在下与氢反应，适当的，在酸受体存在下和在0℃-200℃温度范围内反应(脱卤)，当“X2＝卤素”时，得到的式(I)化合物可用常规的方法分离，而当“X2＝H”时，用质子极性有机液体处理而转化成纯的结晶产物，并通过抽滤除去液体组分而分离出产物。
通式(II)可表示为式(IIA)和(IIB)：
其中
在式(IIA)中
X1和X2如上文定义，和
在式(IIB)中
X1如上文定义和X2只表示氢。
意想不到的是，在氢化脱卤过程中三氟甲氧基基团不会发生变化。更意想不到的特点是，当“X2＝H”时，不需要的异构反应产物3-三氟甲氧基苯磺酰胺可用质子极性有机液体进行简单处理而溶解，从而很容易被除去；而所需要的式(I)产物因为实际上不溶解而留了下来，从而可以通过抽滤很容易地被分离。
本发明的方法极大地丰富了所属领域的技术内容。
式(II)给出了在本发明的方法中用作生产2-三氟甲氧基苯磺酰胺的原料的卤代三氟甲氧基苯磺酰胺的一般定义。
在式(II)中，
X1优选表示氯或溴，和
X2优选表示氢或氯。
当“X2＝H”时，使用的原料是式(IIA)和(IIB)化合物的混合物，优选式(IIA)化合物的量在60％以上。当“X2＝卤素”时，使用的原料是式(IIA)化合物。
式(II，其中X2＝H)的原料是已知的，和/或可按照本身已知的方法制备(参见EP-A23422，EP-A64322)。式(II，其中X2＝卤素)的原料是新的，并且也是本发明的技术主题(参见制备实施例)。

在完成本发明的方法时，醇类，特别是甲醇或乙醇，是特别优选使用的稀释剂。

在本发明的方法中，负载于活性炭上的钯是特别优选使用的催化剂。

在进行本发明的方法时，反应温度可在一基本范围内变化。一般来说，本发明的方法可在0℃和200℃之间进行，优选在20℃和150℃之间，特别优选在40℃和120℃之间进行。
本发明的方法通常在大气压下，或是在提高的压力下进行，优选在1巴和100巴之间，特别优选在1巴和50巴之间进行。
在本发明的优选实施方案中，将式(IIA，其中X2＝卤素)的原料化合物或式(IIA，其中X2＝H)和(IIB)原料化合物的混合物加入适当的稀释剂中，向其中加入催化剂，以及如果需要加入酸受体，将混合物以常规的方式氢化，优选在提高的压力和提高的温度下氢化。
氢化结束后，遗留的氢用氮置换，混合物用水稀释，适当的，进行过滤。浓缩滤液，对残余物[当X2＝H时，其基本组成是2-三氟甲氧基苯磺酰胺和3-三氟甲氧基苯磺酰胺的混合物]进行处理，即用差不多二倍重量的质子极性有机液体一起搅拌。
适当的质子极性有机液体具体的是选择取代的羟烷基化合物。这类物质优选包括醇类如甲醇，乙醇，以及在各种情况下是直链的或支链的丙醇、丁醇、戊醇和己醇，还包括烷氧基醇如甲氧基乙醇和乙氧基乙醇。
为此目的，特别优选使用的是正和异丙醇，以及正、异、仲和叔丁醇。
然后，通过抽滤分离由本发明的方法得到的式(I)的三氟甲氧基-苯磺酰胺结晶。
用本发明的方法生产的式(I)化合物2-三氟甲氧基苯磺酰胺可用作制备具有除草活性的化合物的中间体(参见US4732711)。
