Abstract
Reivindicación 1: Un procedimiento para la eliminación del paladio residual de la fabricación de un compuesto de la fórmula (1) en el que X representa H o F, R¹ representa H ó -C(O)CH₃, y R² representa alquilo C₁₋₁₂ o un arilalquilo C₇₋₁₁ sustituido o no sustituido por una reacción de acoplamiento catalizada por paladio que comprende: (a) poner en contacto el compuesto de la fórmula (1) en un solvente inmiscible en agua con una solución acuosa que contiene desde, aproximadamente un 20 a, aproximadamente un 50 por ciento de un bisulfito de metal alcalino a una temperatura desde, aproximadamente 60 a aproximadamente 90ºC y un pH de aproximadamente 2,0 a aproximadamente 8,0; (b) separar la fase acuosa de la fase solvente inmiscible en agua; y (c) recuperar el compuesto de la fórmula (1) a partir de la fase de solvente inmiscible en agua.
