Method for preparing 5-chloro-4-hydroxypyrimidine, 2-chloro enamine as intermediate in this method, and the use of the compound prepared above (METHOD OF PRFPARING 5-CHLORO-4-HYDROXYPYRIMIDINES, 2-CHLORENAMINES AS INTERMEDIATES IN) THE METHOD, AND USE OF THE COMPOUNDS THUS PREPARED)

摘要

The present invention relates to a process for the preparation of the following general formula (I) compounds by the conversion of chloroacetic acid esters to the corresponding chloroenamines using ammonia or ammonium salts and condensation of the chloroenamines with formamide in the presence of a base. .;The invention also relates to 2-chloroenamine as intermediate of the process.
