Abstract
Procedure for obtaining dibenzazezines, of general formula: **(See formula)** wherein R1 and R2 are the same or different, and represent a member chosen from the group consisting of a hydrogen atom, a hydroxy group, a lower alkoxy group, an aralkoxy group and a hydroxymethyl group; or when they are adjacent and taken together, they can constitute an alkylenedioxy group; R3, R4 and R5, the same or different, represent a member chosen from the group consisting of a hydrogen atom, a hydroxy group and a lower alkoxy group; or two of said radicals, when adjacent and taken together, may constitute an alkylenedioxy group; and R6 is a member selected from the group consisting of an alkyl group, an alkenyl group, an aralkyl group, and a cycloalkyl group; but from the definition given above, the following cases are excluded; While and taken together, they form a 10,11-methylenedioxy group and two of the radicals R3, R4 and R5 are 3- and 4-methoxy groups, the remaining radicals R3, R4 and R5 represent a hydrogen atom and R6'is a methyl group; and while R1 and R2 are 10- and 11-methoxy groups and two of the radicals R3, R4 and R5, taken together, represent a 3,4-methylenedioxy group, the remaining radical R3, R4 and R5 is a hydrogen atom and R6'is a methyl group; and the acid addition salts; characterized in that it comprises submitting a compound of the general formula: (see formula) wherein R1'and R2', the same or different, represent a member chosen from the group consisting of a hydrogen atom, a hydroxy group, a lower alkoxy group, an aralkoxy group and a hydroxymethyl group; or when they are adjacent and taken together, they can constitute an alkylenedioxy group; R3', R4' and R5', the same or different, are chosen from the group consisting of a hydrogen atom, a hydroxy group and a lower alkoxy group; or two of said radicals, when adjacent and taken together, can form an alkylenedioxy group; R6'is a member chosen from the group consisting of an alkyl group, an alkenyl group, an aralkyl group, and a cycloalkyl group; and X is a halogen atom; but from this definition, the special case is excluded in which all radicals R1'to R5' are hydrogen atoms; to Hofmann degradation, followed by reduction or reduction with metal-solvent.
