実験手順

The ethyl 4-(2-aminoethyl)-phenylacetate hydrochloride used as starting material is prepared in the following manner: 4-(2-acetamidoethyl)-acetophenone is reacted with morpholine and sulfur to give the thiomorpholide of 4-(2-acetamidoethyl)-phenylacetic acid (m.p. 117°-118° C.). Subsequent alkaline saponification, followed by esterification with ethanolic hydrochloric acid, gives ethyl 4-(2-aminoethyl)-phenylacetate hydrochloride; m.p. 177°-178° C., after recrystallization from ethanol.
