Condensations between G; methoxy-&aminoquinoline and dialkylaminoalkyl chloride hydro- chlorides usually proceeded satisfactorily at 60'in absolute ethanol. Higher condensation temperatures were unfavorable to good yields. Recrystallizations of the hydrochlorides obtained directly from the reaction mixtures gave better yields and purer products than low pressure distillations of the free bases. The properties and analyses of the salts obtained ...
