Procedure for the synthesis of reactive dyes with the fibers of the formula ** (See formula) ** in which an X means a grouping of the formula ** (See formula) ** the other X means a hydrogen atom or a SO3H group, Y means a hydrogen atom or a methyl group or SO2H. Z means a substituting fibroreactive, preferably heterocyclic, n means an integer value of 2 at least and one at least of the symbols X and Y represents a SO3H group, characterized by preparing such azo dyes by coupling corresponding diazo or tetraazo compounds with di- or tri-sulfonaphthylpyrazole-3-carboxylic acids or by condensation of corresponding aminoazo dyes with acylating agents.
