A process for the preparation of 6-(7-((1-aminocyclopropyl)methoxy)-6-methoxyquinolin-4-yloxy)-N-methyl-1-naphthamide and synthetic intermediates thereof

摘要

A process for the preparation in high yields and purity of the compound 6-(7-((1-aminocyclopropyl)methoxy)-6-methoxyquinolin-4-yloxy)-N-methyl-1-naphthamide of formula (I) and of the pharmaceutically acceptable salts thereof is described. The process has various advantages over those previously described, in particular it avoids the use of acyl azide intermediates and their Curtius rearrangement. Novel intermediates useful for the preparation of compound (I) are also described.
