The present invention relates to a method for preparing 2-Alkoxyphenoxyethanamines and more particularly relates to the preparation of the new chemical entity 2-Alkoxyphenoxyethylacetamides, in particular as intermediates in said method. An industrial process for the synthesis of 2-Alkoxyphenoxyethanamines which is cheap and easy to perform, is a long felt need for those skilled in the art. The object of the present invention is therefore to provide a process for the industrial production of phenoxyethanamine which is cheap and easy to perform. This object is solved by the new chemical entity 2-Alkoxyphenoxyacetamide which is prepared by reacting an ortho substituted phenol with a 2-Alkyloxazoline. By hydrolysis of the acetamide with water in the presence of organic or mineral acids such as hydrochloric acid and/or sulfuric acid, the 2-Alkylphenoxyethanamine is obtained.
本发明涉及一种制备2-烷氧基苯氧
乙胺的方法,更具体地涉及制备新
化学实体2-烷氧基苯氧乙基乙酰胺,特别是作为该方法中的中间体。对于那些熟练的工艺人员来说,一种便宜且易于执行的合成2-烷氧基苯氧
乙胺的工业化过程一直是迫切需要的。因此,本发明的目的是提供一种便宜且易于执行的工业生产苯氧
乙胺的方法。这一目的通过新的
化学实体2-烷氧基苯氧乙酰胺的制备来实现,该化合物是通过将邻位取代
酚与2-烷氧
噁唑啉反应制备的。通过在有机或矿物酸(如
盐酸和/或
硫酸)存在下用
水水解乙酰胺,可以得到2-烷氧基苯氧
乙胺。
