AMINODEMETHOXYLATION IN 3,4-DIHYDROISOQUINOLINES, ISOQUINOLINES, AND ISOQUINOLINIUM SALTS

The substitution of a methoxy group by a methylamino group in 3,4-dihydroisoquinolines, catalyzed by ammonium chloride, takes place when the methoxy group is at the para position but not at the meta position to the imino group, which is a structural fragm
