Abstract
La presente invención se refiere a un procedimiento para la preparación de un compuesto de la fórmula: (VER FIGURA) en donde R es hidrógeno, un alquilo de 1 a 4 átomos de carbono o bencilo; R1 es un alquilo de cadena recta de 1 a 7 átomos de carbono, un alquilo de cadena ramificada de 3 a 7 átomos de carbono, o un cicloalquilo de 3 a 7 átomos de carbono; cada uno de R2, R3 y R4 es hidrógeno o un alquilo inferior de 1 a 5 átomos de carbono; cada uno de R6, R7 y R8 es hidroxi, alquilo inferior de 1 a 4 átomos de carbono, o halógeno; y "n" es 1 ó 2; que comprende, cuando R es bencilo, hacer reaccionar un compuesto de la fórmula: (VER FIGURA) con un compuesto de la fórmula: (VER FIGURA) en un solvente hidrocarburo anhidro, a una temperatura de reflujo y durante aproximadamente dos horas, después de lo cual la mezcla de reacción se concentra, se disuelve en un solvente de alcohol inferior y se trata con borohidruro de sodio, seguido por separación del producto dibenciloxi, cuando R es hidrógeno o un alquilo de 1 a 4 átomos de carbono, hidrogenar el producto dibenciloxi así obtenido, en presencia de un catalizador apropiado.
