Abstract

El invento se refiere a un procedimiento para preparar un compuesto de fórmula (I): (gráfico), en la uqe R es alquilo C1-C6, cicloalquilo C3-C6 o bencilo y en la uqe el radical fenilo de dicho grupo bencilo está opcionalmente sustituido por uno o más sustituyentes seleccionados cada una de forma independiente entre halo, nitro, alquilo C1-C6 amino, y trifluorometilo, que comprende añadir una solución formada por un compuesto de fórmula (II), un halonitrometano y un disolvente orgánico seleccionado entre acetona, dimetilformamida, dimetilacetamida, acetonitrilo, dimetilsulfóxido, N-metilpirrolidinona y dimetoxietano, (gráfico), en la que R es como se ha definido anteriormente, a una mezcla que comprende una base y un disolvente orgánico, siendo dicho disolvente orgánico como se ha definido anteriormente y seleccionandose dicha base entre carbonato potásico, de forma que se produzca un compuesto de fórmula (I) eliminándose cualquier exceso de base de la mezcla de reacción antes de recuperar el producto (I).The invention relates to a process for preparing a compound of formula (I): (graphic), in the uqe R is C1-C6 alkyl, C3-C6 cycloalkyl or benzyl and in the uqe the phenyl radical of said benzyl group is optionally substituted by one or more substituents each independently selected from halo, nitro, C1-C6 alkyl amino, and trifluoromethyl, comprising adding a solution consisting of a compound of formula (II), a halonitromethane and an organic solvent selected from acetone , dimethylformamide, dimethylacetamide, acetonitrile, dimethylsulfoxide, N-methylpyrrolidinone and dimethoxyethane, (graph), in which R is as defined above, to a mixture comprising a base and an organic solvent, said organic solvent being as defined above and said base being selected from potassium carbonate, so that a compound of formula (I) is produced, removing any excess base from the reaction mixture before recovering the product (I).
