The reaction of 1-(p-benzyloxyphenoxy)-2,3-epoxypropane (I) with 4-[N-(2-aminoethyl)carbamoyl]morpholine (II) by means of KOH in isopropanol gives 1-(p-benzyloxyphenoxy)-3-[2-(morpholinocarbonamido)ethylamino]-2-propanol (III), which is debenzylated by treatment with H2 over Pd/C in ethanol acetic acid and treated with a solution of fumaric acid in ethanol.
