Description
技术领域
本发明涉及一种新的制备异硫氰酸吡啶基甲酯的方法及其新中间体。
背景技术
现有制备异硫氰酸吡啶基甲酯的方法是将通式(A)所示吡啶基甲基胺与二硫化碳和例如氯甲酸乙酯在碱如氢氧化钠存在的条件下按下列反应式进行反应：
1)CS2
2)ClCOOC2H5
Py-CH2-NH2→Py-CH2-NCS
(A) 碱
Py＝选择性取代的吡啶基，例如2-氯-5-吡啶基(参见EP-A0 302 389)
然而，上述方法的不利之处在于选用二硫化碳作为反应参与物。此外还会生成氧硫化碳副产物。
发明内容
现已发现制备具有良好产率和高纯度通式(I)所示异硫氰酸吡啶基甲酯的方法，
其中，R1代表卤素或C1-C4-烷基，
第一步反应中，通式(II)所示的胺与通式(III)所示黄原酸盐，如果适宜的话在稀释剂存在下，反应，
其中，R1如上所述，
R2O-CS-SM (III)
其中，
R2代表C1-C4-烷基，优选甲基或乙基，及
M代表碱金属，优选钠和钾，或代表铵，及
第二步反应中，所得通式(IV)所示的二硫代氨基甲酸盐，如果适宜的话在稀释剂存在下，氧化，制得通式(I)的异硫氰酸化合物，
其中，
R1和M分别如上所述。
式(I)为本发明制得的异硫氰酸吡啶基甲酯化合物的通式。此通式中，R1优选为氯或甲基。
令人惊奇地是，式(I)所示异硫氰酸吡啶基甲酯在本发明制备方法中收率良好并且纯度较高，尽管式(III)黄原酸盐中的含硫基团MSH是比醇基团R2OH更好的离去基团，而该反应机制因此本应推断为：
本发明所述制备反应的优越性在于不采用二硫化碳作为反应参与物。此外，反应情况简单(无放热反应)并且反应过程中无副反应。
反应中采用例如5-氨基甲基-2-氯吡啶和乙基黄原酸钾作为起始反应物并以NaOCl水溶液作为氧化剂，本发明所述方法的反应过程如下列反应式所示：
作为本发明所述方法第一步反应中的起始反应物的式(II)所示胺化合物是已知的(参见，例如EP-A 0 391 205或US-P 4 499 097)和/或可通过常规方法制得。
作为本发明方法第一步反应的另一起始反应物的式(III)所示黄原酸盐也是公知化合物。
式(IV)代表本发明所述制备方法第一步反应的产物二硫代氨基甲酸盐的结构通式。此通式中，R1优选为氯或甲基并且M优选为钠，钾或铵。
式(IV)的二硫代氨基甲酸盐是新化合物并且也是本申请的发明主题之一。
本发明所述方法的第二步反应的优选氧化剂是：次氯酸钠或次氯酸钾溶液和铜(II)化合物例如硫酸铜。
本发明所述方法中第一步反应的适宜稀释剂是常规有机溶剂。其中优选烃类，例如甲苯或二甲苯；醚，例如甲基叔丁基醚、甲基叔戊基醚、1，2-二甲氧基乙烷、1，2-二乙氧基乙烷、四氢呋喃或二噁烷；醇，例如甲醇、乙醇、正丙醇、异丙醇、正-、异-、仲-或叔-丁醇；腈，例如乙腈、丙腈或丁腈；以及酰胺，例如二甲基甲酰胺。
进行本发明方法第一步时的反应温度可在相对较宽的范围内变化。通常，反应温度介于30-150℃之间，优选介于50-120℃之间。
在本发明所述方法第一步反应中优选采用等摩尔量反应。然而，反应亦允许价廉的式(III)所示黄原酸盐有相对较大的过量，优选过量100％。
反应结束后生成新的式(IV)所示二硫代氨基甲酸盐并且可用常规方法分离出该化合物(参见：制备实施例)。
本发明所述方法的第二步氧化反应的优选稀释剂是水和另一惰性微水溶的溶剂，例如烃类、氯代烃、醚、腈、酮或酰胺。
本发明所述方法第二步中的反应温度可在相对较宽范围内变化。通常，反应温度介于-30℃-50℃之间，优选介于-10℃-10℃之间。
以每摩尔二硫代氨基甲酸盐计，本发明所述方法第二步反应中所用氧化剂通常是4-5摩尔，优选4-4.5摩尔。
反应结束后得到式(I)的异硫氰酸吡啶基甲酯并且可用常规方法将其分离(参见：制备实施例)。
通过本发明所述制备方法制得的式(I)异硫氰酸吡啶基甲酯可作为制备生物活性化合物例如杀虫剂的中间体(参见：例如EP-A 0 302389)。
具体实施方式
制备实施例
实施例1
(第二步反应)
将51.3g(0.2mol)的2-氯-5-吡啶基甲基二硫代氨基甲酸钾(参见：第一步反应)溶解在200ml水中并再混入200ml的二氯甲烷。
在0℃下，将460ml浓度为13％的NaOCl水溶液维持反应温度不超过5℃滴加到上述溶液中。反应混合物在0-5℃下搅拌30分钟，然后分离出有机相，水相用二氯甲烷萃取三次，合并有机相并用硫酸钠干燥。
蒸除溶剂，在冰箱内结晶出31.3g(为理论产率的82％)的2-氯-5-吡啶基甲基异硫氰酸酯(熔点：22℃)。
(第一步反应)
将2.85g(20mmol)2-氯-5-氨基甲基-吡啶和3.2g(20mmol)乙基黄原酸钾在30ml乙醇中搅拌下回流过夜。
