Abstract
La presente invención se refiere a un proceso para preparar el compuesto de la fórmula I donde el compuesto de la fórmula III se hace reaccionar con cloruro de oxálico y el producto obtenido se trata con hidracina y un hidróxido de metal alcalino en presencia de una fase acuosa a temperatura elevada; luego de concluir el tratamiento, se produce un sistema trifásico por adición de un éter, obteniéndose el compuesto de la fórmula I por acidificación de la fase intermedia. La invención se refiere también a un polimorfo del compuesto de la fórmula I.The present invention relates to a process for preparing the compound of formula I where the compound of formula III is reacted with oxalic chloride and the product obtained is treated with hydrazine and an alkali metal hydroxide in the presence of an aqueous phase at elevated temperature; After concluding the treatment, a triphasic system is produced by adding an ether, obtaining the compound of formula I by acidification of the intermediate phase. The invention also relates to a polymorph of the compound of formula I.
