Abstract

6 - (p - Aminobenzenesulphonamido) - 2 : 4 - di - methyl pyrimidine is prepared from a benzene sulphonic acid halide substituted in the paraposition by a group convertible to an amino group by hydrolysis or reduction and 6-amino-2 : 4-dimethyl pyrimidine, characterised in that at least two molecules of the pyrimidine compound are used for each molecule of the sulphonyl halide. It is stated that by using the reagents in the above proportions, a much higher yield is obtained than if the reagents are used in theoretical proportions. Groups mentioned which may be converted into an amino group by hydrolysis or reduction include the acetylamino group, the nitro group and the azo group. The reaction is preferably carried out in the presence of a diluent such as dioxane or pyridine. In examples, two molecules of 6 - amino - 2 : 4 - dimethylpyrimidine is reacted with in example (1) one mol. of p-nitro-benzene-sulpho-chloride and in example (2) one mol. of p-acetylaminobenzene sulphochloride. Specification 553,205 is referred to.
