| description | La presente invención se refiere a procedimiento para la preparación de los compuestos de la fórmula I, caracterizado porque un compuesto de la fórmula 3, reacción con un agente de halogenación en presencia de un compuesto de la fórmula NA bajo liberación de aniones X- donde R, R1, R2, R3 y (alq) en la fórmula (3) tienen cada vez el significado indicado anteriormente y NA representa el compuesto nitrogenado, no cargado, en que se basa el radical -NA+.
A process for the preparation of compounds of the formula
which is characterised in that a compound of the formula
is reacted with a halogenating agent in the presence of a compound of the formula
NA (2a> and in which the symbols have the meaning indicated in Claim 1, is described. The compounds obtainable by the process are useful coupling components for the synthesis of cationic dyes. |
