Abstract

Procedure for obtaining diazo compounds of formula I, **(See formula)** where one of X1 and X2 signifies the sulfonic acid group, the other signifies a radical of the formula -NH-R3 wherein R3 signifies a radical comprising a heterocyclic radical containing at least one substituent capable of being cleaved as an anion, Y signifies methyl, methoxy or methoxyethoxy Z signifies hydrogen, methyl or methoxy, A signifies a naphthalene radical coupled in the ortho position with the nitrogen and oxygen atoms, and which apart from the sulfonic groups, is unsubstituted or substituted by amino and n means the whole number 2 or 3, characterized in that a compound of formula II is condensed, **(See formula)** wherein Y, Z, A and n are as defined above, and one of Q1 and Q2 signifies the sulfonic acid group the other signifies the amino group, with a compound of formula VIII, R3-W where R3 is as defined above, and W means an acid radical that is cleaved upon condensation with a primary amino group.
