Process for preparing an anti-cancer agent, 1-((4-(4-fluoro-2-methyl-1H-indol-5-yloxy)-6-methoxyquinolin-7-yloxy)methyl)cyclopropanamine, its crystalline form and its salts
The present invention relates a new process to synthesize 1-((4-(4-Fluoro-2-methyl-1H-indol-5-yloxy)-6-methoxyquinolin-7-yloxy)methyl)cyclopropanamine (AL3818). A stable crystalline form of A13818 has been prepared. Salts and their crystalline forms of AL3818 have been also prepared. Anti-cancer and optometric activities of AL3818 and its salts have been further tested. New process has been outlined in Scheme I.
