| titleOfInvention | Process for the preparation of 2-ethoxy-4,6-dihydroxy pyrimidin or their alkaline salts |
| abstract | There is described a process for the preparation of 2-ethoxy-4,6-dihydroxypyrimidine and the alkali metal salt thereof, an important intermediate in the fields of pharmacology and agrochemistry. Reaction of an O-ethylisourea salt formed preferably as an intermediate from cyanamide or chloroform amidinium salts or of the free O-ethylisourea with an alcoholate and a dialkylmalonate or a salt of the dialkyl malonate in alcohol and, if appropriate, subsequent acidification allows this compound to be prepared in good yields and high purity using the process according to the invention. |
