Abstract
La presente invención se refiere a un procedimientde preparación de derivados de 8-amino-teofilina de fórmula (VER FIGURA) en la cual A es un radical alcohileno lineal o ramificado que tiene de 2 a 4 la fórmula general (VER FIGURA) en donde R es un dical alcohileno lineal o ramificado que tiene de X es un número de 2 a 6, e y es un número de 2 a 6, con un compuesto alcanolamina de la fórmula (VER FIGURA) en donde R es un hidrógeno o un radical alquilo de bajo contenido; X es un número de 2 a 6; e y es un número de 0 a 3, en la presencia de una cantidad catalíticamente efectiva, de una substancia que contiene fósforo a temperaturas comprendidas entre 250°C y 350°C bajo una presión suficiente para mantener la mezcla esencialmente en la fase líquida y la recuperación del compuesto poliamina polialquileno, de una mezcla de reacción resultante, caracterizado porque la substancia que comprende fósforo es escogida de los fosfatos de metales acídicos compuestos de ácido fósforico y sus compuendensa una piperazina sustituída de fórmula (VER Fe fosfato, alquilo o arilo, ésteres de fosfato alqinen anteriormente, con un derivado de fórmula (VEo o arilo, y ácido fosfóricos, monosales de metal alcalino, de ácido fosfórico, los tioanálogos de lndose la reacción de condensación mediante fusión de los reactivos juntos, a una temperatura aproximadamente 180 a 190°C.The present invention relates to a process for preparing 8-amino-theophylline derivatives of the formula (SEE FIGURE) in which A is a linear or branched alcoholic radical having from 2 to 4 the general formula (SEE FIGURE) where R is a linear or branched alcoholic dical having X is a number from 2 to 6, and y is a number from 2 to 6, with an alkanolamine compound of the formula (SEE FIGURE) where R is a hydrogen or an alkyl radical of low content; X is a number from 2 to 6; ey is a number from 0 to 3, in the presence of a catalytically effective amount, of a phosphorous-containing substance at temperatures between 250 ° C and 350 ° C under a pressure sufficient to keep the mixture essentially in the liquid phase and the recovery of the polyalkylene polyamine compound, from a resulting reaction mixture, characterized in that the phosphorus-containing substance is chosen from the acidic metal phosphates composed of phosphoric acid and its compounds is a substituted piperazine of the formula (SEE Fe phosphate, alkyl or aryl, esters of phosphate alqinen above, with a derivative of the formula (VEo or aryl, and phosphoric acids, monosalts of alkali metal, of phosphoric acid, the thio analogues of the condensation reaction by melting the reagents together, at a temperature of approximately 180 to 190 ° C.
