Abstract

Las cetoamidas son intermediarios utiles para la preparacion de antagonista del receptor CCR5. Específicamente revela un proceso para sintetizar 1-(2,4-dimetilpirimidin-5-carbonil)-4-piperidona, 1-[(2,4-dimetil-3-piridinil)carbonil]-4-piperidona y compuestos relacionados de reaccion. Reivindicacion 1: Un proceso de preparacion de una cetoamida de formula (1), donde R1 es un sustituyente seleccionado de los sustituyentes alquilo, arilo, cicloalquilo, heteroarilo y heterociclilo, con la condicion de que R1 no contenga una amina primaria o secundaria, comprendiendo dicho proceso: i) hacer reaccionar un ácido carboxílico de formula (2), con un reactivo clorante para sustituir un radical hidroxi por un átomo de cloro en el ácido carboxílico, utilizando un catalizador y un solvente aprotico para producir una solucion del cloruro de ácido de formula (3), ii) preparar en forma separada un medio de reaccion multifásico con una fase salina concentrada acuosa y una fase orgánica que comprende un solvente aprotico apropiado y el compuesto de formula (3), y agregar dicha solucion de cloruro de ácido al medio de reaccion para dar la cetoamida de formula (1).
