The synthetic route is as follows., category: imidazoles-derivatives

A solution of 5,6-difluoro-1 H-benzo[d]imidazole (1.4 g, 9 mmol), 2-bromo-4-(bromomethyl) benzonitrile (2.5 g, 9 mmol) [see Example 1 Step A] and K2C03 (3.8 g, 27 mmol) in CH3CN (50 mL) was heated at 25C for 12 hours. The reaction mixture was cooled to 25C, filtered and concentrated under reduced pressure. The residue was purified by silica gel chromatography using Petroleum ether:EtOAc (30: 1-3:1 ) as eluting solvents to afford 2-bromo-4-((5,6-difluoro-1 H- benzo[d]imidazol-1-yl)methyl)benzonitrile as a yellow solid (1.3 g, 39%). MS (ESI) m/z: 348 [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 78581-99-4.
