Sažetak

When B-ethoxy-a-phthalimido-DL-propionyl chloride [I] was condensed with benzene in the presence of anhydrous aluminum chloride, B-ethoxy-a-phthalimido-DL-propiophenone [II] was obtained in a yield of 2.3%. Melting point 110° (under previous softening at 106°). [I] gave with diphenylcadmium the same ketone, which was isolated in the form of 2,4-dinitrophenylhydrnzone, in a yield of 3.5 %. Melting point 192-195°.
