Reference of 4887-83-6, A common heterocyclic compound, 4887-83-6, name is 7-Methyl-1H-benzo[d]imidazole, molecular formula is C8H8N2, 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.
Example 8 2-[(4-methyl-1H-benzo[d]imidazol-1-yl)methyl]-3-phenyl-4H-chromen-4-one To a solution of intermediate 5 (0.10 g, 0.317 mmoles) in dioxan (2 ml), was added 4-methylbenzimidazole (0.083 g, 0.634 mmoles) at RT and refluxed for 12 h. The reaction mixture was cooled, diluted with aqueous bicarbonate solution and extracted with ethyl acetate. The organic layer was dried over sodium sulphate and concentrated under reduced pressure. The crude product was purified by column chromatography with methanol:dichloromethane to afford the title compound as yellow solid (0.060 g, 51% yield). MP: 204-208 C. 1H-NMR (delta ppm, DMSO-D6, 400 MHz): delta 8.11 (s, 1H), 8.04 (d, J=7.6 Hz, 1H), 7.77 (t, J=7.6 Hz, 1H), 7.55 (m, 7H), 7.08 (t, J=8.0 Hz, 1H), 6.99 (d, J=7.6 Hz, 2H), 5.40 (s, 2H), 2.48 (s, 3H). Mass: 367.25 (M++1).
The synthetic route of 4887-83-6 has been constantly updated, and we look forward to future research findings.
