Abstract

Mejoras en un procedimiento para la preparación de triciclazol, cuyo procedimiento consiste en hacer reaccionar 2-hidrazino-4-metilbenzotiazol con ácido fórmico en exceso, caracterizándose dichas mejoras porque el producto se recupera agregando un disolvente aromático hidrocarbonado a la mezcla de reacción, separando azeotrópicamente el exceso de ácido fórmico con el disolvente aromático hidrocarbonado y recuperando el triciclazol del disolvente.
