Electric Literature of 53557-69-0, 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 53557-69-0, name is 6-Iodopyrimidin-4-amine. This compound has unique chemical properties. The synthetic route is as follows.
Description 94; 6-(1 8-Naphthyridin-2-yl) pvrimidin-4-amine; To a mixture of Description 92 (2.52 g, 15. 3 mmol), hexamethylditin (5.0 g, 15.3 mmol), lithium chloride (1.95 g, 45.9 mmol), and copper (I) iodide (291 mg, 1.53 mmol) in anhydrous 1,4-dioxane (50 ml) was added Pd (PPh3) 4 (884 g, 0.77 mmol). The mixture was de-gassed three times, and heated at 100C overnight. The mixture was cooled and diluted with EtOAc (120 ml) and washed with a 10% potassium fluoride solution (200 ml). The organic layer was washed with sat. NaCl (50 ml), dried over Na2SO4, filtered, and evaporated. The residue was taken up in anhydrous 1,4-dioxane (75 ml), and Description 93 (1.55 g, 7 mmol), lithium chloride (1.78 g, 42 mmol), and copper (I) iodide (266 mg, 1.4 mmol) added, followed by Pd (PPh3) 4 (808 mg, 0.7 mmol). The mixture was de-gassed 3 times and heated at 100C for 3 days. The mixture was poured into water (200 ml), and extracted with EtOAc (2 x 100 ml), the combined EtOAc layers were washed with water (150 ml), sat. NaCl (100 ml), dried over Na2SO4, filtered and evaporated. The residue was purified by column chromatography on silica (eluent: 2% MeOH in DCM + 0.5% NH40H) to give the title compound (100 mg, 3%).’H NMR (360 MHz, DMSO-d6) 7.18 (2 H, br s), 7.66-7. 86 (3 H, m), 8.55 (1 H, dd, J 8.1 and 1. 8), 8. 58 (1 H, d, J4. 2), 8.64 (1 H, d, J8. 4), 9.16 (1 H, dd, J4. 2 and 2.1).
According to the analysis of related databases, 53557-69-0, the application of this compound in the production field has become more and more popular.
