Abstract
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.
