NIST chemical information Information provided by: webbook.nist.gov (external link)
use 4, 6-dichloropyrimidine is an intermediate of the fungicide azoxystrobin.
Used as a pharmaceutical intermediate to produce sulfa-6-methoxine.
Used as the synthesis of pharmaceutical intermediates
The starting material for the synthesis of disubstituted pyrimidine through tandem amination and Suzuki-Miyaura cross-coupling reactions; also used in the synthesis of diaryl pyrimidine involving diaryl cross-coupling reactions
Production method It is obtained by cyclization and chlorination of dibutyl malonate.
the preparation method is to refluxing with propanediamide and formamide in the presence of sodium ethoxide for 2h, cooling to obtain precipitation, filtering to obtain 4, 6-dihydroxypyrimidine, and then chlorination of dried 4, 6-dihydroxypyrimidine in the presence of phosphorus oxytrichloride to obtain a product.
