Abstract
Un método para preparar 2,3-dicloropiridina y los intermediarios 3-amino-2-cloropiridina y 3-aminopiridina. Reivindicacion 1: Un método para preparar 2,3-dicloropiridina de formula (1), caracterizado porque comprende los pasos de: a) poner en contacto 3-amino-2-cloropiridina de formula (2) o una solucion que comprende 3-amino-2-cloropiridina de formula (2), con ácido clorhídrico para formar una sal de ácido clorhídrico de 3-amino-2-cloropiridina; b) poner en contacto la sal de ácido clorhídrico de 3-amino-2-cloropiridina con una sal nitrito para formar una sal de cloruro de diazonio correspondiente; y c) poner en contacto la sal de cloruro de diazonio correspondiente con ácido clorhídrico en presencia de un catalizador de cobre donde al menos aproxidamente50 % del cobre es cobre en estado de oxidacion II, opcionalmente en presencia de un solvente orgánico, para formar 2,3-diclopiridina de formula (1).
