Abstract

Un método para la preparacion de 5-cianoftalida en el cual 5-carboxiftalida es convertida en la correspondiente amida de Formula 1 en la cual R eshidrogeno o alquilo C1-6, que luego se hace reaccionar con un agente deshidratante obtenido de ese modola 5-cianoftalida. La conversion de 5-carboxiftalida ala correspondiente amida de Formula 1 puede llevarse a cabo por medio del correspondiente alquilo C1-6 o éster fenílico o el cloruro ácido, que es convertidoa la amida de formula 1 medianteamidac ion con amoníaco o una alquilamina C1-6. Mediante el proceso 5-Cianoftalida, un importante intermediario utilizado enla preparacion del fármaco antidepresivo citalopram, es preparada con altos rendimientos mediante un procedimientoconveniente y efec tivo en cuanto al costo.
