摘要： Compounds of the formula ##STR1## where R.sub.1, R.sub.2 and R.sub.3 are each independently of the others hydrogen, C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy, halogen or C.sub.1 -C.sub.4 alkanoylamino,R is hydrogen or unsubstituted or C.sub.1 -C.sub.4 alkoxy substituted C.sub.1 -C.sub.12 alkyl or an --(alk)--NA.sup..sym. X.sup..crclbar. radical or,R forms together with an R.sub.1 in the ortho-position relative to the amino group a partially hydrogenated, substituted or unsubstituted 5- to 7-membered heterocyclic ring which may contain additional N, S or O atoms as ring members, (alk) is a substituted or unsubstituted C.sub.1 -C.sub.6 alkylene radical,--NA.sup..sym. is the radical of an amino compound of formula ##STR2## where R.sub.4, R.sub.5 and R.sub.6 are each independently of the others substituted or unsubstituted C.sub.1 -C.sub.6 alkyl, substituted or unsubstituted C.sub.7 -C.sub.12 aralkyl or substituted or unsubstituted aryl, R.sub.8 and R.sub.9 are each independently of the other substituted or unsubstituted C.sub.1 -C.sub.6 alkyl, and R.sub.10 and R.sub.11 are each independently of the other hydrogen, substituted or unsubstituted C.sub.1 -C.sub.6 alkyl, substituted or unsubstituted C.sub.7 -C.sub.12 aralkyl or substituted or unsubstituted aryl, or is the positively charged radical of a 5- to 7-membered aliphatic or aromatic heterocycle which may contain additional N, S or O atoms as ring members, and X.sup..crclbar. is a halide ion, are prepared by reacting a compound of the formula ##STR3## with a halogenating agent in the presence of a compound of the formulaNA (2a) where the symbols are as defined in claim 1, these compounds being useful coupling components for the synthesis of cationic dyes.
