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., Formula: C4H5BrN2
Preparation 14 Methyl-3-(1-methyl-imidazol-5-yl)-2-naphthoate To a mixture of methyl-3-(4,4,5,5,-tetramethyl-1,3,2-dioxaborolan-2-yl)-2-naphthoate (Preparation 13) (15.37 g, 49.3 mmol) and 5-bromo-1-methyl-1H-imidazole (9.06 g, 49.3 mmol) in toluene/EtOH (350 mL/36 mL) were added Pd(PPh3)4 (11.37 g, 9.84 mmol), Na2CO3 (20.9 g, 197.2 mmol) and water (106 mL). The mixture was degassed, purged with N2, and heated to reflux for 20 hours. It was then cooled to RT, neutralized with HCl (1.0 N, 100 mL), and concentrated in vacuo. The residue was partitioned between water (300 mL) and EtOAc (1 L). The organic layer was washed with water (2 L) and brine, dried over MgSO4, filtered and evaporated in vacuo. The resulting crude material was submitted to flash chromatography (1.5% MeOH/CHCl3), furnishing the title compound as a light-yellow solid (9.5 g, 72%).
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.
