| titleOfInvention | Method for the production of 2-amino-4-chloro-6-alkoxypyrimidines |
| abstract | The invention relates to a method for producing 2-amino-4-chloro-6-alkoxypyrimidines by reacting 2-amino-4,6-dichloropyrimidine with an alkali alcoholate or a mixture of alkali hydroxides and an alcohol in a polar aprotic solvent (mixture), whereupon the solvent is distilled off to > 30 percent and the product is precipitated by adding water during or following the distillation process. The inventive method, in which especially acetone is used as a polar aprotic solvent and which can be carried out at temperatures between 5 and 60 °C, allows 2-amino-4-chloro-6-alkoxypyrimidines and above all 2-amino-4-chloro-6-methoxypyrimidine to be produced in a particularly economical and environmentally friendly manner while obtaining high yields and a very distinctive purity. |
