Abstract

Proveer un método para producir ácido 2,6-dietil-4-metilfenilacético. Un método para producir ácido 2,6-dietil-4-metilfenilacético caracterizado porque comprende una etapa de hacer reaccionar un haluro de 2,6-dietil-4-metilfenil magnesio con óxido de etileno para obtener 2-(2,6-dietil-4-metilfenil) etanol y una etapa de oxidar el 2-(2,6-dietil-4-metilfenil)etanol; y la etapa de oxidar el 2-(2,6-dietil-4-metilfenil)etanol. La oxidación se conduce en presencia de un compuesto radical nitroxilo y con mayor preferencia en presencia de una sal de un ácido hipohaloso y/o una sal de un ácido haloso.Provide a method to produce 2,6-diethyl-4-methylphenylacetic acid. A method for producing 2,6-diethyl-4-methylphenylacetic acid characterized in that it comprises a step of reacting a 2,6-diethyl-4-methylphenyl magnesium halide with ethylene oxide to obtain 2- (2,6-diethyl- 4-methylphenyl) ethanol and a step of oxidizing 2- (2,6-diethyl-4-methylphenyl) ethanol; and the step of oxidizing 2- (2,6-diethyl-4-methylphenyl) ethanol. The oxidation is conducted in the presence of a nitroxyl radical compound and more preferably in the presence of a salt of a hypohalous acid and / or a salt of a haloso acid.
