Ein Verfahren zur Herstellung von Verbindungen der Formel
worin R Wasserstoff, Methyl oder Aethyl, X ein Mono-, Di-oder Trifluor-pyrimidinrest und n = 1 oder 2 ist, welches dadurch gekennzeichnet ist, dass man 1-Amino-8-hydroxynaphthalin-sulfonsäuren der Formel
mit Di-, Tri- oder Tetrafluor-pyrimidinen in wässriger Lösung oder Suspension bei pH > 7 kondensiert, gibt Verbindungen der Formel (1) in hoher Ausbeute; die Verbindungen der Formel (1) eignen sich als Zwischenprodukte zur Herstellung von Rekativfarbstoffen.
Certain dicarboxylic acids, e.g. oxalic, malonic, maleic, fumaric and phthalic acids, are useful in promoting the coupling of aromatic diazonium or tetrazonium compounds in positions ortho and/or para to the amino group in aminonaphthol sulphonic acids or naphthylamine sulphonic acids.
