| titleOfInvention | Process for producing 2-amino-4,6-dichloropyrimidine |
| abstract | The present invention relates to an industrially advantageous process for producing 2-amino-4,6-dichloropyrimidine, which comprises reacting 2-amino-4,6-dihydroxypyrimidine or its salt with phosphorus oxychloride at a temperature of from 50 to 100 DEG C in the presence of a solvent and an acid removing agent. Further, the yield of 2-amino-4,6-dichloropyrimidine can be improved by hydrolyzing 4,6-dichloro-2-pyrimidinylphosphoramidic dichloride produced as a by-product of the chlorination reaction to form 2-amino 4,6-dichloropyrimidine. The 2-amino-4,6-dichloropyrimidine produced by the process of the present invention is useful as an intermediate for medicines and agricultural chemicals. |
