Process for preparing 5-chloro-4-hydroxypyrimidines |
| abstract |
A process for preparing 5-chloro-4-hydroxypyrimidines, 2-chloro enamines as intermediates in this process and their use The invention relates to a process for preparing compounds of the formula ##STR1## in which R 1 is optionally substituted alkyl, cycloalkyl, aryl or benzyl, in which a chloroacetic ester is converted with ammonia or an ammonium salt into the corresponding chloro enamine and the latter is condensed in the presence of a base with formamide. The invention furthermore relates to 2-chloro enamines as intermediates in the process. |
