| titleOfInvention | Process for the preparation of 4,6-dihydroxypyrimidine |
| abstract | The invention relates to a process for the preparation of 4,6-dihydroxypyrimidine by reacting malonic diester with formamide and alkali alcoholate. The malonic acid ester, alone or simultaneously with the total amount or a partial amount of the formamide, is added in portions or continuously with temperature control to the alkali alcoholate presented as a solution or suspension in an alcohol alone or together with the total amount or the remaining partial amount of the formamide. A temperature of 102 to <120 ° C. is then set for 10 to <60 minutes. Working up after the holding time in the temperature range mentioned is then carried out in a manner known per se. |
