Abstract
Un proceso para la preparacion de un compuesto de la formula (I) donde R1 y R2 son cada uno independientemente H, halogeno, alquilo C1-6 o haloalquiloC1-6; R3 es H o alquilo C1-4; y R4 y R5 son independientemente H, alquilo C1-6, haloalquilo C1-6 o cicloalquilo C1-6; y sus isomeros opticos, que comprendehacer reaccionar al compuesto de haluro de ácido fenoxi de la formula (II), donde X es halogeno y R1, R2 y R3 son como se describimos para la formula (I) conal menos un equivalente molar de un compuesto de amino nitrilo de la formula (III) donde R4 y R5 son como describimos para la formula (I) ante la presencia deun carbonato de metal alcalino acuoso o bicarbonato de metal alcalino acuoso o sus mezclas, opcionalmente ante la presencia de unco-solvente. En general, losprocesos conocidos para preparar a los derivados del fungicida N-(1-cianoalquil)-2-fenoxipropionamida provocan un sistema no acuoso que utiliza una base deamina orgánica, como por ejemplo trialquilamina. Sin embargo, al fabricar en escala, el uso de irritantes como por ejemplo aminas orgánicas volátiles provocauna gran cantidad de afluente que requiere un tratamiento costoso y pasos de recuperacion. Un proceso alternativo para preparar dichos derivados depropionamidautiliza NaOH acuoso al 10% como base. Sin embargo, el uso de una base fuerte como por ejemplo NaOH aumenta la velocidad de formacion desubproductos no deseados como por ejemplo la formacion de ácido fenoxipropionico correspondiente del cloruro de ácido de partida. Este subproducto no deseadono es transportado en el producto de amida deseado. Más aun, dicho subproducto es un derivado herbicida conocido y podría, por lo tanto, contaminar el productofungicida deseado con un compuesto fitotoxico. Esta contaminacion sería perjudicial para el uso del producto en la práctica de la produccion de cultivos. Porlo tanto, se proporciona un proceso mejorado, economico y eficiente para la preparacion de los derivados de N-(1-cianoalquil)-2-fenoxipropionamida. Dichosderivados de propionamida se producen con un rendimiento mayor y una pureza mejoradas.
