Application of 26830-94-4, The major producers of chemicals have been the Europe, Japan and China. Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a compound 26830-94-4, name is 2,6-Dichloropyrimidine-4-carbonyl chloride. This compound has unique chemical properties. The synthetic route is as follows.
To a solution of 2,6-dichloropyrimidine-4-carbonyl chloride (26.13 g, 123.6 mmol) in Et2O (500 mL) was added a mixture of 0.5M ammonia in dioxane (250 mL, 125 mmol) and iPr2NEt (22 mL, 126 mmol) dropwise over approximately 50 minutes. After stirring overnight the reaction was concentrated in vacuo to a residue and chromatographed over silica gel with 10-50% EtOAc in hexanes. The product fractions were evaporated in vacuo, and the resulting solid residue triturated with 10 mL 10% EtOAc/hexanes and filtered to give 2,6-dichloropyrimidine-4-carboxamide as an orange crystalline solid (9.743 g, 50.74 mmol, 41 % yield). LC/MS: m/z= 192.2[ +H]+, 1H NMR (400 MHz, DMSO-d6): 8.40 (1 H, br s), 8.16 (1 H, br s), 8.10 (1 H, s).
According to the analysis of related databases, 26830-94-4, the application of this compound in the production field has become more and more popular.
