Process for preparing N-(amino-4,6-dihalogenpyrimidine)formamides
A halogenated hydrocarbon solvent is used in the production of 2,5-diamino-4,6-dihalo-pyrimidines (I) by reaction of 2,5-diamino-4,6-dihydroxy-pyrimidine (II) or its salts with a phosphorus oxyhalide and a quaternary ammonium halide. A halogenated hydrocarbon solvent is used in the production of 2,5...

Zusammenfassung: | A halogenated hydrocarbon solvent is used in the production of 2,5-diamino-4,6-dihalo-pyrimidines (I) by reaction of 2,5-diamino-4,6-dihydroxy-pyrimidine (II) or its salts with a phosphorus oxyhalide and a quaternary ammonium halide. A halogenated hydrocarbon solvent is used in the production of 2,5-diamino-4,6-dihalo-pyrimidines of formula (I) by reaction of 2,5-diamino-4,6-dihydroxy-pyrimidine of formula (II) or its salts with a phosphorus oxyhalide and a quaternary ammonium halide. X = halo. |
