Abstract

2-aminobenzene-sulphonic acid N-trichloropyrimidylamide is made by catalytic hydrogenation of 2-nitro-benzene-sulphonic acid N-trichloro-pyrimidylamide which is obtained by condensing 2-nitrobenzene-sulphonamide with 2:4:5:6-tetrachloropyrimidine.ALSO:The invention comprises organic dyes which contain at least one group of formula <FORM:0952068/C3/1> where each X is hydrogen or a substituent and R is hydrogen, alkyl, hydroxyalkyl, alkoxyalkyl or acyl. The dyes may be of the monoazo, polyazo or metallized azo, anthraquinone, phthalocyanine, triphenylmethane, nitro or dioxazine series. Substituents specified for X are halogen, methyl, nitro and carbomethoxy. The dyes are made by condensing an organic dye containing a -SO2-NHR- group with a pyrimidine of the formula <FORM:0952068/C3/2> by condensing an organic dyestuff sulphony1 halide with a pyrimidine of the formula <FORM:0952068/C3/3> or, in the case of azo dyes, by condensing pyrimidine derivatives of the formula II or III above with a diazo component or a coupling component and coupling these with coupling or diazo components respectively. Examples are given. The dyes dye, pad and print wool, silk, nylon and leather from acid, neutral or weakly alkaline media and cellulose fibres in an alkaline medium.
