| titleOfInvention | Process for the preparation of 4,6-dichloropyrimidine |
| abstract | A process for preparing 4,6-dichloropyrimidine from 4,6-dihydroxypyrimidine in the presence of a tertiary amine base characterised in that phosgene is added to a mixture of 4,6-dihydroxypyrimidine and a tertiary amine of formula R<1>R<2>R<3>N (wherein R<1>, R<2> and R<3> are, independently C1-10 alkyl, phenyl, a 3-7 membered carbon nitrogen heteroaryl group or phenyl(C1-4)alkyl) in a chlorinated solvent, wherein the molar ratio of 4,6-dihydroxy-pyrimidine:base:phosgene is in the range 1:(0.8 to 2.5):(2.5 to 3.6). |
