Abstract
Procedimiento para preparar un compuesto de formula general: **formula** en donde r1 representa una cadena alquilo lineal o ramificada, alquenilo o alquinilo conteniendo de 3 a 6 átomos de carbono, y r2 y r3, los cuales puede ser iguales o diferentes, cada uno representa hidrógeno o halógeno o un grupo metilo, metoxi, nitro o trifluorometilo o r2 y r3 forman juntos un grupo metilendioxi o etilendioxi; con la condición de que r2 y r3 no son ambos átomos de hidrógeno; y sales de los mismos farmacológicamente aceptables formadas con una base de metal alcalino o una base orgánica conteniendo nitrógeno, el cual comprende la reacción de un 5,6-diamina de la formula general iv de la primera reivindicación.Procedure to prepare a compound of general formula: ** formula ** where r1 represents a linear or branched alkyl, alkenyl or alkynyl chain containing from 3 to 6 carbon atoms, and r2 and r3, which may be the same or different, each represents hydrogen or halogen or a methyl, methoxy, nitro or trifluoromethyl group or r2 and r3 together form a methylenedioxy or ethylenedioxy group; with the proviso that r2 and r3 are not both hydrogen atoms; and pharmacologically acceptable salts thereof formed with an alkali metal base or an organic nitrogen-containing base, which comprises the reaction of a 5,6-diamine of general formula iv of the first claim.
