Abstract
Un método para la preparación de citalopram que comprende los pasos de hacer reaccionar un compuesto de Fórmula IV en la cual R 1 es alquilo C1-C6 y X es O o NH, en forma sucesiva con un reactivo de Grignard de 4-halógenofluorofenilo, con lo que se obtiene un compuesto de Fórmula IVa en la cual R 1 y X son como se define anteriormente, y un reactivo de Grignard de 3-halógeno-N,N-dimetilpropilamina, efectuar el cierre de anillo del compuesto resultante de Fórmula V en la cual R 1 y X son como se define anteriormente, y convertir el compuesto resultante de Fórmula VI donde R 1 y X son como se define anteriormente, en el correspondiente derivado 5-ciano, es decir citalopram, el cual se aísla como la base o como una de sus sales farmacéuticamente aceptables.
