Adding a certain compound to certain chemical reactions, such as: 4179-19-5, name is 3,5-Dimethoxytoluene, belongs to ethers-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 4179-19-5, HPLC of Formula: C9H12O2
1,3-dimethoxy-5-methylbenzene (30 g, 0.20 mol) and dichloromethane (900 mL) were added to a dry round bottom flask (1 L) and cooled to the above solution in an ice bath. Disulfone chloride (52.5 g, 0.40 mol) was added dropwise, and the mixture was added dropwise and stirred at room temperature overnight. After the reaction was completed, an aqueous solution of sodium hydrogencarbonate was added dropwise to adjust pH = 8, and dichloromethane was extracted with dilute hydrochloric acid, respectively.Washed with distilled water,Drying and concentration under reduced pressure gave compound 2,4-dichloro-1,5-dimethoxy-3-methylbenzene (31 g, white solid).
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 3,5-Dimethoxytoluene, other downstream synthetic routes, hurry up and to see.
