Related Products of 302964-08-5 ,Some common heterocyclic compound, 302964-08-5, molecular formula is C16H13Cl2N5OS, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc., below Introduce a new synthetic route.
To a mixture of the starting material 7H (150 mg, 0.38 mmol), dioxane (8 mL) were added piperidine (97 mg, 1.14 mmol, 3 eq) and DIEA (147 mg, 1.14 mmol, 3 eq) at room temperature. The mixture was stirred at 90-91 C. under nitrogen for 15 h. LC-MS analysis showed the product peak. The mixture was not a clear solution. The mixture was concentrated to dryness and suspended in 50 mL acetonitrile containing 20% HPLC grade water. The mixture was then centrifuged at 4000 rpm for 15 min. The pellet was re-suspended in acetonitrile and centrifuged again at 4000 rpm for 15 min. The final pellet was dried under nitrogen to afford the target compound VIII (H-20) (?129 mg) as an off-white solid. LC-MS: 443.14 (M+H); 1H NMR (DMSO-d6): 11.52 (s, 1H. NH), 9.82 (s, 1H, NH), 8.18 (s, 1H), 7.39 (m, 1H), 7.21 (m, 2H), 6.00 (s, 1H), 3.55 (m, 4H), 3.22 (s, 3H), 2.43 (s, 3H), 1.65 (m, 6H).
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles. 302964-08-5, 2-((6-Chloro-2-methylpyrimidin-4-yl)amino)-N-(2-chloro-6-methylphenyl)thiazole-5-carboxamide, other downstream synthetic routes, hurry up and to see.
