Abstract

Un método para la preparacion de citalopram, que comprende las etapas de: a) someter un compuesto de formula (IV), donde R es un grupo de formula (II)donde R1 y R2 se seleccionan independientemente entre alquilo inferior, arilo y heteroarilo, o bienR1 y R2 están unidos y juntos determinan una cadena de 4 o5 miembros que opcionalmente comprende un átomo de S, O o N, o 4,5-dihidro-1,3-oxazol-2-ilo opcionalmente sustituido en la posicion 4 y/o 5 con uno o másgrupos alquilo inferior, arilo ohetero arilo, a hidrolisis reductora; y b) convertir el 5-formil compuesto resultante de formula (V) en el 5-ciano compuestocorrespondiente, citalopram de formula (I) que es aislado como la base o una sal farmacéuticamente aceptable del mismo;intermediario para la preparacion decitalopram, composicion farmacéutica antidepresiva y uso del intermediario para la preparacion de citalopram. El citalopram es una droga antidepresiva muyconocida. Es un inhibidor selectivo de la recaptacion deserotonina (5-hi droxitriptamina; 5-HT) que actua centralmente y, en consecuencia, tiene actividadantidepresiva.
