Description
本申请是申请号为：01810522.x，申请日为2001年6月7日、发明名称为“农药化合物的制备方法”的母案的分案。
技术领域
本发明涉及一种制备取代吡唑化合物的方法。
背景技术
吡唑如5-氨基-1-芳基-3-氰基吡唑化合物及其衍生物，例如Fipronil，可以形成一类重要的杀虫剂。正如WO 00/35884和美国专利5,556,873所揭示的，某些取代5-N-烷基-N-烷氧乙酰氨基-1-芳基-3-氰基吡唑化合物具有有价值的杀虫性。
发明内容
我们已经研制了一种新的生产在制备取代吡唑农药化合物中有用的中间体化合物的合成路线。
因此本发明提供一种制备通式(I)所示化合物的方法，
式中：
n为1，X为碳原子；
R1为CN或CSNH2；
R2为氢或氯；
R3为卤素、卤代烷基、卤代烷氧基或SF5；
所述方法包括将通式(II)所示化合物和质子源反应，
其中n、X、R1、R2和R3如上所述。
用于本发明方法中的质子源宜为酸性水溶液例如盐酸水溶液。
所述反应宜在适当的溶剂或者在能或不能和水部分混溶的溶剂中进行。适当的溶剂包括烃类溶剂如甲苯或二甲苯。
所述反应用的质子源用量宜为0.1～2当量，更好为0.5～1.0当量。
所述反应宜在-50～200℃，更好为50～100℃的温度下进行。
至于R1、R2和R3，R1宜为CN，R2宜为氯，R3宜为卤代烷基，尤其是三氟甲基。
化合物(II)可以通过新颖合成路线制备，根据本发明的另一方面，提供一种制备上述化合物(II)的方法，该方法包括将通式(III)所示化合物和季铵盐反应，
其中n、X、R1、R2和R3如上所述。
所述季铵盐可以是四烷基铵的卤化物如碘化物或溴化物，更好为溴化四烷基铵。适当的溴化四烷基铵包括溴化四丁基铵。所述反应用的卤化物盐用量宜为0.01～2当量，更好为0.1～0.5当量。
所述反应宜在能或不能和水部分混溶的有机溶剂中进行。适当的溶剂包括烃类溶剂如甲苯或二甲苯。所述反应宜在50～100℃的温度下进行。
上述化合物(III)可以由已知包括将具有通式(IV)所示的Fipronil吡唑化合物和原甲酸三甲酯反应的合成路线制备。
此反应可以在酸性催化剂存在下进行。适当的催化剂包括对甲苯磺酸。
化合物(III)也可以用季铵盐处理，接着酸处理直接制备化合物(I)，而不需要离析化合物(II)。
化合物(I)也可以通过将Fipronil(化合物IV)和甲醛或甲醛三聚体或其化学等价物反应由此形成中间体化合物(V)来制备，
其中n、X、R1、R2和R3如上所述。
然后中间体化合物(V)可以和还原剂反应形成化合物(I)。合适的还原剂包括硼氢化钠。所述还原剂的用量可以是1～5当量。
通式(II)、(III)和(V)的某些化合物是新颖的化合物，根据本发明的另一方面尤其提供如下新颖的化合物：
3-氰基-1-(2，6-二氯-4-三氟甲基苯基)-5-N-(甲酰基-N-甲氨基)-4-(三氟甲基亚硫酰基)吡唑(化合物II)，
3-氰基-1-(2，6-二氯-4-三氟甲基苯基)-5-(甲氧基亚甲基氨基)-4-(三氟甲基亚硫酰基)吡唑(化合物III)，
3-氰基-1-(2，6-二氯-4-三氟甲基苯基)-5-羟甲氨基-4-(三氟甲基亚硫酰基)吡唑(化合物V)。
本发明方法制备的化合物(I)可以用作原料用于形成更重要的已知具有杀虫性的吡唑，如以下通式(VI)所示：
式中：
R1为CN或CSNH2；
X为N或CR4；
R2和R4各自为氢或氯；
R3为卤素、卤代烷基、卤代烷氧基或-SF5；
R5和R6各自为烷基；
n为0，1或2。
已知在本文所参考的国际专利申请号WO 00/35884中记述了由化合物(I)制备此化合物的方法。更具体的说是化合物(I)在三乙胺存在下和乙氧乙酰氯反应制备化合物(VI)。
具体实施方式
现在，将参考以下非限制性实施例说明本发明。
实施例1
在回流下，在0.5当量对甲苯磺酸存在下使摩尔过量的原甲酸三甲酯和Fipronil(化合物IV)反应，制备3-氰基-1-(2，6-二氯-4-三氟甲基苯基)-5-(甲氧基亚甲基氨基)-4-(三氟甲基亚硫酰基)吡唑(化合物III)。
此产物立即在100℃的二甲苯中用0.1当量碘化四丁基铵处理5小时，形成3-氰基-1-(2，6-二氯-4-三氟甲基苯基)-5-(N-甲酰基-N-甲氨基)-4-(三氟甲基亚硫酰基)吡唑(化合物II)。将此介质立即和盐酸水溶液反应形成最终产物3-氰基-1-(2，6-二氯-4-三氟甲基苯基)-5-甲氨基-4-(三氟甲基亚硫酰基)吡唑(化合物I)。
实施例2
将5当量甲醇钠(30％甲醇溶液)迅速加入0.437克Fipronil和1.4当量低聚甲醛在3毫升甲醇的悬浮液中，在20℃反应3小时和60℃反应1小时后形成3-氰基-1-(2，6-二氯-4-三氟甲基苯基)-5-羟甲氨基-4-(三氟甲基亚硫酰基)吡唑(化合物V)。然后往此介质中加入1当量硼氢化钠，经过常规提取和色谱分离后形成3-氰基-1-(2，6-二氯-4-三氟甲基苯基)-5-甲氨基-4-(三氟甲基亚硫酰基)吡唑(化合物I)。
