Application of 3034-42-2,Some common heterocyclic compound, 3034-42-2, name is 1-Methyl-5-nitroimidazole, molecular formula is C4H5N3O2, 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.
To a solution of compound 1(2.9 g, 22.83 mmol) in THF (35 mL) was added LiHMDS (1.0 M THF solution, 24 mL, 24 mmol) at -40 C under argon. The mixture was stirred at -40 C for 15 minutes.The aldehyde was added slowly with inner temperature kept below -30 C. The mixture was stirred at – 40 C for 75 minutes before quenched with aqueous saturated NH4C1 solution (10 mL).The reaction mixture was extracted with EtOAc (40 mL x 3), washed with brine (50 mL), dried over Na2504.The solvents were removed under reduced pressure and the residue was purified via flash column to afford clear oil (1.5 g, yield 33%).1HNJIVIR (CDC13, 400 IVIHz) : 7.97 ( s, 1H), 4.22 (m, 1H), 4.00 (s, 3H), 2.24-2.14 (m, 1H), 1.06 (d, J = 6.4 Hz, 3H), 0.93 (dd, J = 1.2, 6.4 Hz, 3H)
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 1-Methyl-5-nitroimidazole, its application will become more common.
