然而该方法得到相应的反式衍生物;顺式衍生物的制备方法尚未有描述。

式(Ⅰ)N-取代的顺-N-丙烯基乙酰胺用于制备2-氯-5-甲基吡啶。
优选用本发明方法制备的式(Ⅰ)化合物是式中取代基如下定义的化合物:R1代表可任选地被C1-C2烷氧基取代的C1-C6烷基;或代表1-丁烯-4-基,2-丁烯-4-基;丙炔基或丁炔基;或代表环丙基,环丁基,环戊基,环己基,环丙基甲基,环丁基甲基,环戊基甲基或环己基甲基;或代表苄基,苯基乙基,苯基丙基,萘基甲基,噻吩基甲基或吡啶基甲基,它们各自均可任选地被相同的或不同的取代基单取代至三取代,在所有情况下均可提及的取代基是卤素、C1-C4烷基和C1-C4烷氧基。

式(Ⅱ)给出了在用于制备式(Ⅰ)化合物的本发明方法中用作原料的乙酰胺类的总定义。在式(Ⅱ)中,R1优选或特别优选具有上面关于作为优选的或特别优选的式(Ⅰ)新化合物的R1的描述中已经述及的那些意义。
式(Ⅱ)乙酰胺是已知的和/或可用本身已知的方法(参见例如DE-OS(德国公开说明书)2334632或J.Chem.Soc.Perkin Trans.Ⅰ 1993,2344)来制备。

后处理可按常规方法用水来进行。在将碱中和后,将混合物用适当的溶剂萃取。化合物可用蒸馏法纯化。若使用催化量的碱而不使用溶剂或使用适宜于下一步骤的溶剂,则化合物可不经分离和纯化直接进一步反应得到式(Ⅳ)2-氯-5-甲基吡啶。
可用按照本发明的异构化法制备的式(Ⅰ)N-取代的顺-N-丙烯基乙酰胺可以通过与式(Ⅲ)甲酰胺衍生物和氯化剂反应制得式(Ⅳ)2-氯-5-甲基吡啶。

式(Ⅲ)甲酰胺衍生物是公知的有机合成用化学制品。
制备式(Ⅳ)2-氯-5-甲基吡啶的方法用氯化剂来实施。常规氯化剂可用于此目的,例如磷酰氯,氯化磷(Ⅴ),光气,草酰氯,亚硫酰氯,全氯丁酰氯,二氯苯并间二氧杂环戊烯(dichlorobenzodioxol),氯化N,N-二甲基-氯甲基亚铵(immonium)或氯化N,N-二乙基-氯甲基亚铵。
实施制备式(Ⅳ)2-氯-5-甲基吡啶的方法的适宜的稀释剂是常规有机溶剂,尤其包括脂族、脂环族或芳族可任选地被卤代的烃类,例如汽油、苯、甲苯、二甲苯、氯苯、二氯苯、石油醚、己烷、环己烷、二氯甲烷、氯仿、四氯甲烷;醚类,例如乙醚、异丙醚、二氧六环、四氢呋喃或乙二醇二甲醚或乙二醇二乙醚;腈类,例如乙腈、丙腈或丁腈;醚胺类;例如N,N-二甲基甲酰胺、N,N-二甲基乙酰胺、N-甲基N-甲酰苯胺、N-甲基吡咯烷酮或六甲基磷酰三胺;亚砜类,例如二甲亚砜。和砜类,例如四氢噻吩砜。
在进行式(Ⅳ)2-氯-5-甲基吡啶的制备时,反应温度可在相当宽的范围内变动。一般来讲,该过程在-30-+150℃、最好在-10-+120℃之间的温度进行,起始阶段最好在-10-+40℃之间进行,而后续阶段在+20-120℃之间进行。然而还可以直接在高温下进行该过程并就地制备“Vilsmeier试剂”。
该过程在大气压下进行。但也可以在加压或减压、一般是在0.1-10巴之间的压力下进行。
为实施式(Ⅳ)2-氯-5-甲基吡啶的制备方法,每摩尔式(Ⅰ)N-取代的顺-N-丙烯基乙酰胺一般使用在1-10mol之间、最好是在1.5-5.0mol之间、特别是在2.0-4.0mol之间的氯化剂和在1-10mol之间、最好是在2.0-4.0mol之间的式(Ⅲ)甲酰胺衍生物。
