title ketimines containing a fluorine atom at position 2 of the phenyl group are efficiently cyclized under mild conditions to N-[2-(dimethylamino)ethyl]-2-(2-fluorophenyl)quinolin-4-amines by the reaction with a lithiumreagentderivedfrom N,N-dimethylethylenediamine. The facile regioselective displacement of C2-F in the presence of another fluorine atom at the phenyl group by the same reagent or
