Synthetic Route of 71759-89-2, A common heterocyclic compound, 71759-89-2, name is 5-Iodo-1H-imidazole, molecular formula is C3H3IN2, 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 1; [4-(1-{3-[2-(3-phenylsulphonylamino-phenyl)-2-hydroxy-ethylamino]-3-methyl-butyl}-1H-imidazol-4-yl)-phenyl]-acetic acid-hydrotrifluoroacetate; a. Tert-butyl [3-(4-iodo-imidazol-1-yl)-1,1-dimethyl-propyl]-carbamate; 3.88 g (20 mmol) 4-iodoimidazole are dissolved in 30 ml DMPU and at 5 C., 556 mg (22 mmol) 95% sodium hydride are added batchwise. After the development of gas has died down the reaction mixture is stirred for 1 hour at 10 C. Then a solution of 4.44 g (20 mmol) tert-butyl (3-chloro-1,1-dimethyl-propyl)-carbamate in 5 ml DMPU and 739 mg (2.0 mmol) tetrabutylammonium iodide are added. The reaction mixture is stirred for 16 hours at ambient temperature and then heated to 80 C. for 24 hours. After cooling to ambient temperature the reaction solution is poured onto a mixture of 500 ml ice water and 250 ml of ethyl acetate. The aqueous phase is separated off and extracted with ethyl acetate. The combined organic phases are washed with water and saturated aqueous sodium chloride solution, dried on sodium sulphate and evaporated down using the rotary evaporator. The residue is chromatographed on silica gel (petroleum ether/ethyl acetate=80:20?0:100).Yield: 1.66 g (22% of theory)C13H22IN3O2 (379.24)Mass spectrum: (M+H)+=380Rf value: 0.45 (silica gel; petroleum ether/ethyl acetate=1:1)
The synthetic route of 71759-89-2 has been constantly updated, and we look forward to future research findings.
