Reaction Steps

The preparation of the ethyl 4-(2-aminopropyl)-phenylacetate used as starting material is carried out in the following manner: 4-(2-acetamidopropyl)-acetophenone (m.p. 99°-100° C.) is reacted with morpholine and sulfur to give the thiomorpholide of 4-(2-acetamidopropyl)-phenyl-acid acid (m.p. 147° C.). By boiling with 6 N hydrochloric acid, there is obtained 4-(2-aminopropyl)-phenylacetic acid (oily), which is esterified with hydrogen chloride and ethanol. By treating the initially formed hydrochloride with dilute aqueous sodium hydroxide solution, there is obtained the free amino compound in the form of an oil.
