18800-30-1, name is 1-Bromo-4-(2-bromoethoxy)benzene, belongs to ethers-buliding-blocks compound, is considered to be a conventional heterocyclic compound, which is widely used in drug synthesis. The chemical synthesis route is as follows. Computed Properties of C8H8Br2O
l-Bromo-4-(2-bromoethoxy)benzene (95 mg, 0.34 mmol) was added to a mixture of N-[2-(3-azetidinyloxy)-5,6-dichloro-3-pyridinyl]-2-chloro-4-pyridinecarboxamide (i.e. the product of Step C) (100 mg, 0.28 mmol) and N,N-diisopropylethylamine (76 mL, 0.42 mmol) in acetonitrile (3 mL), and the reaction mixture was heated at 60 C overnight. The cooled solution was treated with saturated aqueous sodium bicarbonate solution (2 mL) and water (2 mL), and then diluted with dichloromethane before being filtered through a tube containing Celite diatomaceous filter aid, eluting with dichloromethane. The residue after concentration was purified by chromatography (silica gel, ethyl acetate to 5% methanol in ethyl acetate) to give the title product, a compound of the present invention, as a pale yellow oil (84 mg)..H NMR delta 8.88 (s, 1H), 8.62 (d, 1H), 8.28 (br s, 1H), 7.77 (d, 1H), 7.62 (d, 1H), 7.37 (d, 2H), 6.78 (d, 2H), 5.35 (m, 1H), 3.99 (t, 2H), 3.92 (t, 2H), 3.42 (br s, 2H), 2.95 (t, 2H).
The synthetic route of 18800-30-1 has been constantly updated, and we look forward to future research findings.
