Application of 302964-08-5, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 302964-08-5, name is 2-((6-Chloro-2-methylpyrimidin-4-yl)amino)-N-(2-chloro-6-methylphenyl)thiazole-5-carboxamide, molecular formula is C16H13Cl2N5OS, The compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.
To a mixture of the starting material 7H (150 mg, 0.38 mmol) and dioxane (8 mL) were added (S)-pyrrolidin-3-ol hydrochloride (141 mg, 1.14 mmol, 3 eq) and DIEA (245 mg, 1.90 mmol, 5 eq) at room temperature. The mixture was then stirred at 90-92 C. under nitrogen for 12 h. LC-MS analysis showed the product peak. The mixture was not a clear solution. The mixture was cooled to room temperature and concentrated to dryness under reduced pressure, and the resultant residue was suspended in 50 mL acetonitrile, and centrifuged at 4000 rpm for 15 min. The pellet was then suspended in cooled 80% acetonitrile, and centrifuged at 4000 rpm for 15 min. The pellet was re-suspended in cooled 80% acetonitrile, and centrifuged at 4000 rpm for 15 min. The supernatants were combined and concentrated to dryness to afford the target compound X (H-31) (105 mg) as an off-white solid. LC-MS: 445 (M+H); 1H NMR (DMSO-d6): 11.40 (s, 1H. NH), 9.83 (s, 1H, NH), 8.19 (s, 1H), 7.40 (m, 1H), 7.24 (m, 2H), 5.80 (s, 1H), 4.98 (s, 1H), 4.35 (s, 1H), 2.53 (s, 3H), 2.20 (s, 2H), 2.12 (s, 2H), 1.85 (m, 2H).
While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 302964-08-5, 2-((6-Chloro-2-methylpyrimidin-4-yl)amino)-N-(2-chloro-6-methylphenyl)thiazole-5-carboxamide.
