Abstract

SE PONE A PUNTO UN NUEVO PROCEDIMIENTO PARA LA PRODUCCION DE 2-CLORO-5-METIL-PIRIDINA A PARTIR DE 1-OXI-3-METIL-PIRIDINA. EL NUEVO PROCEDIMIENTO SE CARACTERIZA PORQUE LA REACCION SE LLEVA A CABO EN PRESENCIA DE UNA SUSTANCIA DE CLORACION DE FORMULA GENERAL (III) EN LA QUE R ELEVADO 1 ES ALQUILO, HALOGENOALQUILO, CICLOALQUILO, UN ARILO EVENTUALMENTE SUSTITUIDO, NR (AL CUADRADO) R ELEVADO 3 O OR ELEVADO 4, EN DONDE R (AL CUADRADO) Y R ELEVADO 3 SIGNIFICAN POR SEPARADO ALQUILO, CICLOALQUILO O ARILO O, JUNTOS, ALCANODIILO O OXAALCANODIILO, R ELEVADO 4 SIGNIFICA ALQUILO, CICLOALQUILO O UN ARILO EVENTUALMENTE SUSTITUIDO, EN PRESENCIA DE UN COMPUESTO BASICO ORGANICO DE NITROGENO Y EN PRESENCIA DE UN DILUYENTE, A TEMPERATURAS ENTRE -20 C Y +150 C, SIENDO ELABORADO A CONTINUACION EL PRODUCTO DE REACCION DE LA MANERA HABITUAL. LA 2-CLORO-5-METIL-PIRIDINA ES UN PRODUCTO INTERMEDIO PARA LA PRODUCCION, ENTRE OTROS, DE FARMACOS O TAMBIEN DE INSECTICIDAS.
