Abstract
A process for the preparation of 2-naphthylamine derivatives of formula I: ** (Formula) ** where R1 and R2, which may be the same or different, each represent a hydrogen atom, an alkoxy group or, when are attached, R1 and R2 represent an alkylenedioxy group; R3 represents a hydrogen atom, an alkyl group or a cycloalkyl group; R4, R5 and R6, which may be the same or different, each represent a hydrogen atom, an alkoxy group, an alkyl group, a halogen atom, a hydroxyl group, or when two of the radicals R4 are attached, R5 and R6 represent an alkylenedioxy group; and A represents a straight or branched chain alkylene group, of 2 to 10 carbon atoms or an alkylene group of 2 to 10 carbon atoms and interrupted with an oxygen atom that forms a bond therein, and its addition salts therapeutically useful acids.
