These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 24988-36-1, its application will become more common.
Some common heterocyclic compound, 24988-36-1, name is 1,5-Dibromo-2,4-dimethoxybenzene, molecular formula is C8H8Br2O2, 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. Recommanded Product: 24988-36-1
Bisdimethylaminoethyl ether (2.84 g) was dissolved in 42 mL THF and cooled in an ice bath. Isopropylmagnesium chloride (8.9 mL of a 2 M solution in THF) followed by Compound 14 (5 g dissolved in 5 mL THF) were added slowly sequentially. The mixture was allowed to warm to ambient temperature and stirred overnight. Next, 2.1 mL of 3-chloro-2-fluorobenzaldehyde was added. After stirring for ~ Ih, the mixture was quenched to pH ~ 7 with 2N HCl. The product was extracted into ethyl acetate and the organic phase was dried over sodium sulfate. The solvent was exchange to heptane to precipitate the product and a mixture of heptanes:MTBE (4:1) was added to form a slurry. After filtration the solid was slurried in toluene, filtered and vacuum dried to yield compound 15: 1U NMR (CD3CN, 400 MHz) delta 7.47 (s, IH), 7.41-7.35 (m, 2H), 7.15 (t, J = 7.4 Hz, IH), 6.66 (s, IH), 6.21 (br s, IH), 3.90 (s, 3H), 3.87 (br s, IH), 3.81 (s, 3H).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 24988-36-1, its application will become more common.
