6,9-Dichloro-2-methoxyacridine is used to prepare 6-chloro-2-methoxy-acridin-9-ylamine by reacting with phenol and ammonium carbonate. It is used in the preparation of 9-amino-6-chloro-2-methoxyacridine, N'-(6-Chloro-2-methoxy-acridin-9-yl)-heptylamine and N,N'-bis-(6-chloro-2-methoxy-acridin-9-yl)-hexane-1,6-diamine. Further, it is involved in the preparation of 4-aminoquinoline and 9-aminoacridine derivatives by reaction with quinolizidinylalkylamines.
Crystallise it from *benzene or 1,2-dichloroethane (m 162-163o). [Hall & Turner J Chem Soc 697 1945, Beilstein 21 III/IV 1553.]
