Abstract
La presente invención se refiere a un procedimiento para la preparación de ácido 4-(3,4-diclorofenil)-4-fenilbutanoico, que comprende las siguientes etapas: a) someter el ácido 4-(3,4-diclorofenil)-4-cetobutanoico a la acción selectiva de un agente reductor del carbonilo en un disolvente prótico polar o en un disolvente aprótico, a una temperatura de 0 a 100 grados C aproximadamente, hasta que la reacción de reducción para formar el ácido 4-(3,4-diclorofenil)-4-hidroxibutanoico intermedio deseado es prácticamente completa; b) convertir el hidroxiácido intermedio formado en la etapa (a) en 5-(3,4-diclorofenil)-dihidro-2(3H)-furanona y c) a continuación, hacer reaccionar el compuesto de gamma-butirolactona resultante formado en la etapa (b) con benceno en un exceso de dicho reactivo como disolvente o en un disolvente orgánico inerte a la reacción, en presencia de un catalizador del tipo Friedel-Crafts, a una temperatura de 0 a 100 grados aproximadamente, hasta que es prácticamente completa la alquilación del benceno por el compuesto de gamma-lactona antes mencionado para formar el ácido 4-(3,4-diclorofenil)-4-fenilbutanoico deseado.
