Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 1003-21-0, name is 5-Bromo-1-methyl-1H-imidazole, This compound has unique chemical properties. The synthetic route is as follows., Recommanded Product: 1003-21-0
5-Bromo-1-methyl-1H-imidazole (1.36 mL, 0.5 M in DCM over 3 A molecular sieves, 0.678 mmol) was treated with EtMgCl (0.325 mL, 2.09 M in THF, 0.678 mmol) dropwise under argon with stirring at room temperature over 1 minute, and the resulting translucent/semi-opaque reaction was stirred at room temperature for 20 minutes. This was treated dropwise over 2 minutes with a solution of 3-benzyl-6-(4-fluorobenzoyl)-N-methyl-4-(trifluoromethyl)quinoline-2-carboxamide (90.4 mg, 0.194 mmol, Intermediate 35: step f) in DCM (1.2 mL) with stirring at room temperature, and the resulting orange reaction was immediately stirred at 40 C. for 13 hours. The resulting orange opaque mixture was cooled to room temperature, partitioned with 5 M aqueous NH4Cl (3 mL), and the aqueous layer was extracted with DCM (1*5 mL). The combined organic layers were dried (Na2SO4), filtered, and concentrated. The residue was dry load flash chromatographed using 2:3 toluene/acetone (isocratic elution) to yield the title compound as a pale yellow foam. 1H NMR (400 MHz, CDCl3) delta ppm 8.32 (s, 1H), 7.88 (d, J=9.09 Hz, 1H), 7.69 (d, J=10.61 Hz, 1H), 7.30-7.38 (m, 3H), 7.10-7.24 (m, 4H), 6.97-7.09 (m, 4H), 6.29 (s, 1H), 4.91 (s, 2H), 3.39 (s, 3H), 2.89 (d, J=5.05 Hz, 3H); MS m/e 549.2 [M+H]+.
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 1003-21-0.
