With the rapid development and complex challenges of chemical substances, the synthesis of new drugs is usually one of the most effective ways to increase yield.49845-33-2, name is 2,4-Dichloro-5-nitropyrimidine, molecular formula is C4HCl2N3O2, molecular weight is 193.9756, as common compound, the synthetic route is as follows.Application In Synthesis of 2,4-Dichloro-5-nitropyrimidine
Example A3 a). Preparation i of intermediate..1.1; A solution of cyclohexanamine (0.062 mol) in iV,JV-dimethylacetamide (20 ml) was added dropwise to a cooled (-100C) solution of 2,4-dichloro-5-nitropyrimidine (0.062 mol) and DIPE (8.1 g) in 7V,7V-dimethylacetamide (80 ml), then the reaction mixture was allowed to reach room temperature overnight, yielding intermediate 11 (contains regio-isomer; used as such in the next reaction steps).
