Abstract

Process for the production of ethambutol, characterized by condensing 2 moles of a (+) - 2-hydroxylamino-1-butanol (i') with 1 mole of glyoxal (II), in the presence of an appropriate solvent, at a temperature between 0ºC and the boiling point of the solvent used and for a period of a few minutes to a few hours, to obtain a (+) - glyoxal-bis-1-butanol-2-nitrona (III), according to the scheme ** (see formula) ** Where r = h, alkyl, lower acyl or benzyl and by subjecting the nitrone iii to reduction in the presence of an appropriate catalyst, to form ethambutol, which is isolated and purified as it is or is transformed into its non-toxic pharmacologically acceptable salts.
