March 1965 tassium carbonate solution which was separated and extracted with methylene chloride. The combined organic extracts were dried and the solvent was removed. The residue crystallized

By means of hydrolysis, decarboxylation and treatment with phosphorus oxychloride, the ethyl quinaldates were converted to the corresponding 4-chloro-3-halo derivatives which were condensed with 4-diethylamino-l-methylbutylamine. Reductive dehalogenation which occurred in the at-tempts to condense the 4-chloro-3-iodoquinolines with 4-diethylamino-l-methylbutylamine is reported. These same iodoquinolines were successfully condensed with 3-diethylamino-2-hydroxypropylamine by using lower temperatures.
