Abstract

Un procedimiento de preparación de un derivado de 2,3-dicianopirazina de fórmula general **fórmula** en donde A representa un átomo de hidrógeno, un grupo alcohilo inferior, un grupo fenilo sin substituir o substituido, un grupo bencilo o un grupo de fórmula ZR1 en la que Z representa un átomo de oxígeno o azufre, y R1 representa un grupo alcohilo inferior sin substituido substituido, un grupo alquenilo inferior, un grupo alquinilo inferior, un grupo fenilo sin substituido o substituido o un grupo bencilo sin substituir substituido; y B2 representa un grupo de la fórmula ZR1 antes definida o un grupo de fórmula **fórmula** en la que R2 y R3, independientemente uno de otro representan un átomo de hidrógeno, un grupo alcohilo inferior sin substituido o substituido, un grupo alquenilo inferior, un grupo cicloalcohilo, un grupo fenilo sin substituido o substituido, o un grupo bencilo sin substituir o substituido, con la condición de que R2 y R3 no representan un átomo de hidrógeno al mismo tiempo, o R2 y R3 pueden formar un anillo heterocíclico de 3 a 7 eslabones juntamente con el átomo de nitrógeno al que están unidos, conteniendo facultativamente dicho anillo heterocíclico un heteroátomo adicional, que comprende hacer reaccionar un derivado de 2,3-diciano -5- halopirazina de fórmula**fórmula** en la que A es como se ha definido anteriormente, y X3 representa un átomo de halógeno, con un compuesto de fórmula HB2 (VI) en donde B2 es como se ha definido anteriormente, llevándose a cabo esta reacción en un disolvente inerte a temperatura relativamente baja, de menos de 80ºC, en presencia de un agente que captura el haluro de hidrógeno durante un periodo de tiempo que va desde 10 minutos a 2 horas aproximadamente.
