A process for preparation of 3-amino-2-hydroxy-1-propyl ether of the formula ##STR1## wherein R.sup.1 is substituted or unsubstituted alkyl, substituted or unsubstituted aryl, or substituted or unsubstituted heterocyclic ring, R.sup.2 and R.sup.3 are the same or different hydrogen atom, a substituted or unsubstituted alkyl, or may form a ring together with an adjacent nitrogen atom, which ring may be interrupted with nitrogen atom, oxygen atom or sulfur atom, which is characterized in reacting an epoxy compound of the formula ##STR2## wherein X is halogen, in the presence of a fluoride salt, with an alcohol and then reacting an amine. According to the above method, an intermediates for synthesis of medicines is obtained in good yield and highly optical purity.
一种制备式为##STR1##的3-氨基-2-羟基-1-丙基醚的方法,其中R.sup.1是取代或未取代的烷基、取代或未取代的芳基,或取代或未取代的杂环环,R.sup.2和R.sup.3是相同或不同的氢原子、取代或未取代的烷基,或者与相邻的氮原子一起形成环,该环可以被氮原子、氧原子或硫原子中断,其特征在于在存在氟化盐的情况下,将式为##STR2##的环氧化合物与醇反应,然后再与胺反应。根据上述方法,可以获得合成药物的中间体,收率高且光学纯度高。
