In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 7051-16-3, name is 1-Chloro-3,5-dimethoxybenzene belongs to chlorides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below. category: chlorides-buliding-blocks
3-Chloro-5-methoxy-phenol3-Chloro-5-methoxy-phenolSodium methanelhiolate (3.04 g, 43.37 mmol), was added to a solution of l-chloro-3.5- dimethoxy benzene (5.0 g, 28.96 mmol) in 20 ml of l-Methyl-2-Pyrrolidone and the reaction mixture was heated at 140 C for 2.5 h then stirred at room temperature over night. l-Methyl-2-pyrrolidone was removed under reduced pressure and the material partitioned between ethyl acetate/water/lN hydrochloric acid. The organic layer was washed twice with IN hydrochloric acid, brine, dried over sodium sulfate and solvent removed under reduced pressure to give a yellowish solid. The solid was purified by column chromatography (silica gel 60-120 mesh, 10:90 ethylacetate:hexane) to afford 3- Chloro-5-methoxy-phenol in 76.4 % yield.MS [M-H] 157.2, ? NMR (400 MHz, CDCI3) delta (ppm): 6.455-6.500 (d, 2H, J=I8.0 Hz), 6.291 (s, 1H), 4,978 (s, III), 3.767 (s, 3H).
The synthetic route of 7051-16-3 has been constantly updated, and we look forward to future research findings.
