Abstract
La presente invención se refiere a un procedimiento para la preparación del polimorfo I de diclorhidrato de lesopitrón, caracterizado porque una solución de diclorhidrato de lesopitrón en un alcohol alifático de 1 a 4 átomos de carbono, mono o polihidroxilado, a la temperatura de reflujo, se enfría lentamente a 50-55ºC, causando cristalización; se prosigue el enfriamiento lento hasta 0-5ºC; la masa cristalina se filtra y el polimorfo I de diclorhidrato de lesopitrón obtenido se seca a 45ºC. Dicho alcohol alifático es etanol. Los nuevos polimorfos I y II de diclorhidrato de Lesopitrón se caracterizan por sus espectros infrarrojo y difractogramas de Rayos-X. Asimismo comprende las formas I-hidrato y II-hodrato, que se obtienen de los correspondiente polimorfos, que poseen un contenido en agua del 3 al 6% y del 1,5 al 2,5%, respectivamente. Tales productos se utilizan en medicina humana principalmente por su actividad farmacológica sobre el sistema nervioso central. La figura 1 es el compuesto denominado genericamente Lesopitrón.
