Abstract
本发明提供了一种用于制备通式(I)的三氟甲基乙酰苯的新方法，通式(I)中芳香环上的CF3基团的位置可以是在相对于乙酰基的2或3位，该方法包括：(a)使通式(II)的三氟甲基苯甲酰氯与通式(III)的环形仲胺在用来作为酸受体的碱水溶液存在下反应，通式(II)中芳香环上CF3基团的位置可以是相对于乙酰基的2或3位，Hal是选自氟、氯、溴和碘的卤原子，通式(III)中A是一个可以间插着氧或硫原子的C3－C7亚烷基桥键，反应结果形成通式(IV)的环烷基三氟甲基苯甲酰胺，其中CF3基团在芳香环上的位置和A的定义同上，以及(b)向该环烷基三氟甲基苯甲酰胺中加入甲基卤化镁，随后用酸化剂水溶液酸化，形成式(I)的三氟甲基乙酰苯。
Description
本发明涉及制备三氟甲基乙酰苯类、特别是制备3-三氟甲基乙酰苯的方法。
过去已使用几种方法制备3-三氟甲基乙酰苯，但是它们都不适合大规模的工业制造，大规模的工业制造方法应当是简单和有效的方法，能够由市场上容易得到的试剂出发，以高产率和高纯度提供三氟甲基乙酰苯。
本发明提供了一种使用容易得到的原料以高产率和高纯度制备三氟甲基乙酰苯的方法。另外，该方法还具有环境保护方面的优点。
本发明方法包括两个步骤：(a)使三氟甲基苯甲酰卤与环形仲胺在碱水溶液存在下反应，形成环烷基三甲基苯甲酰胺，和(b)向该苯甲酰胺中加入甲基卤化镁，随后用乙酸水溶液酸化，形成产物。使用环胺的好处是由于胺的循环使用而减少了废物。
本发明提供了制备通式I的三氟甲基乙酰苯的方法
其中芳香环上的CF3基团的位置可以是相对于乙酰基的2位或3位，该方法包括
(a)通式II的三氟甲基苯甲酰卤与通式III的环胺在作为酸受体的碱水溶液存在下反应
其中芳香环上CF3基团的位置可以是相对于乙酰基的2位或3位，Hal是选自氟、氯、溴和碘的卤原子，其中A是C3-C7亚烷基桥键，它可以间插着氧或硫原子，反应的结果形成通式IV的环烷基-三氟甲基苯甲酰胺其中芳香环上CF3基团的位置及A同以上定义，和
(b)向该环烷基-三氟甲基苯甲酰胺加入甲基卤化镁，随后用酸化剂水溶液酸化，形成式I的三氟甲基乙酰苯。
在本发明的一项优选实施方案中，使用此方法制备3-三氟甲基乙酰苯。
式III的环形仲胺特别有助于这样制备的三氟甲基乙酰苯的高产率和高纯度。
环形仲胺通常代表吡咯烷、哌啶(未被取代的或者有2、3或4位被低级烷基如甲基或乙基取代)，或者最好是吗啉或硫代吗啉。
步骤(a)和(b)的反应通常都在从室温左右(+20℃至25℃)至约+60℃的中等温度下进行。反应物三氟甲基苯甲酰卤是已知的。在实施本发明中特别适用的是3-三氟甲基苯甲酰氯。可作为酸受体使用的碱的实例是氢氧化钠、氢氧化钾、碳酸钾、碳酸氢钾、碳酸钠、碳酸氢钠、碳酸钙、氢氧化钙、氧化锌、氧化钙及其混合物的约5-70％浓度的水溶液。环胺可以是以上定义的式III范围之内的任何环胺和它们中的一种或多种的混合物，但不限于所给出的实例。特别适用于本发明方法的是哌啶和吗啉。本发明方法优选在惰性溶剂中进行，例如醚，如乙醚、甲乙醚、叔丁基甲基醚、四氢呋喃、二氧杂环己烷等。
用于本发明的格氏试剂是采用甲基作为烷基取代基的格氏试剂。典型的代表是I-Mg-CH3、Br-Mg-CH3和Cl-Mg-CH3。
酸化优选用乙酸进行。但在本发明方法中也可以使用其它的酸化剂，例如盐酸、硫酸和氯化胺。
本发明的高纯产物促进了它作为中间体用于制造重要的农用杀真菌剂α-甲氧亚胺基-2-[[[[1-[3-(三氟甲基)苯基]乙烯基]氨基]氧]甲基]苯乙酸甲酯(trifloxystrobin)。
以下实施例说明了本发明。它们并不被认为是以任何方式限制权利要求的范围。实施例1
向装有搅拌器、两上加液漏斗、冷凝管和加热套的750ml烧瓶中加入88g水和45g吗啉。在搅拌下向此混合物中同时加入104.3g(0.5mol)3-三氟甲基苯甲酰氯和40.8g50％NaOH水溶液。加料期间pH保持在9-10之间，温度保持在+40℃和+55℃之间。加完后，将混合物在搅拌下加热30分钟，至55～60℃。加入75g甲苯后，弃去下面的水层。在搅拌下向烧杯中再加入甲苯和水。放置几分钟后，再次去掉下部的水层。减压蒸除上部有机层的溶剂。完全去掉有机层中的甲苯后，分离出4-(3-三氟甲基苯甲酰)吗啉并用于实施例2中。实施例2
向装有搅拌器、冷凝管、干燥氮气氛装置和液面下加料管的1升烧瓶中加入310g四氢呋喃、18g镁屑和少量碘晶体。将混合物在温和的搅拌下加热至+50℃。通过液面下加料管向此混合物中加入41.1g氯甲烷，保持温度在+50℃和+60℃之间。将得到的甲基卤化镁冷却到+30℃。在搅拌下向此格氏试剂溶液中于1-2小时内加入溶在四氢呋喃中的4-(3-三氟甲基苯甲酰)吗啉(如实施例1中制得的)。加完后将混合物加热至+35～+40℃并搅拌18小时。
向另一只有类似装备的1升烧瓶中加入90g乙酸和205g水。在搅拌下将上述的格氏试剂混合物加到这个第二只烧瓶中。然后使所形成的混合物分层。去掉下部的水层，用饱和盐水将上部的有机层洗几次，然后将有机层在减压下加热以除掉四氢呋喃。除去溶剂后，将产物混合物减压蒸馏，得到纯度98％的3-三氟甲基乙酰苯。
