Electric Literature of 53484-16-5,Some common heterocyclic compound, 53484-16-5, name is 6-Bromo-1-methyl-1H-benzo[d]imidazole, molecular formula is C8H7BrN2, 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.
3.1. Compound A 2-[4-[(3-methylbenzimidazol-5-yl)amino]phenyl]acetonitrile A mixture of Pd2(dba)3 (0.01 mmol) and Xantphos (0.01 mmol) in 1,4-dioxane (1 mL) was sonicated and added under nitrogen to a mixture of 6-bromo-1-methyl-benzimidazole (0.45 mmol), 2-(4-aminophenyl)acetonitrile (0.58 mmol) and Cs2CO3 (0.62 mmol) in 1,4-dioxane (2 mL). The mixture was stirred at 110° C. for 12 h. The mixture was diluted (DCM), washed (H2O), dried (phase separator and concentrated. The residue was purified by prep HPLC to yield the desired product (Compound A). MW: 262.3. MS Ms’d: 263.2. NMR: 1H NMR (400 MHz, DMSO-d6): delta=8.13 (1H, s), 7.68 (1H, dd), 7.60 (1H, dd), 7.54 (1H, d), 7.32 (1H, d), 7.24 (1H, t), 6.91 (1H, dd), 3.77 (3H, s), 3.39 (3H, s).
The synthetic route of 53484-16-5 has been constantly updated, and we look forward to future research findings.
