Abstract

The new compound 5,5-dichloro-4,5-dihydro-6-hydroxy-2-trichloromethylpyrimidin-4-one can be prepared by reacting 4,6-dihydroxy-2-methylpyrimidine or chlorinated subsequent stages with a chlorinating agent. 5,5-dichloro-4,5-dihydro-6-hydroxy-2-trichloromethylpyrimidin-4-one can be used as an intermediate for the preparation of 2-trichloromethyl-4,5,6-trichloropyrimidine.
