Adding a certain compound to certain chemical reactions, such as: 39021-83-5, name is 1,4-Dimethoxy-2,3-dimethylbenzene, 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 39021-83-5, Safety of 1,4-Dimethoxy-2,3-dimethylbenzene
Step 2 A solution of 1,4-dimethoxy-2,3-dimethyl-benzene (1 g) in dichloromethane was stirred and cooled in an ice-water bath, and TiCl4 (1.1 mL) was slowly added, followed by the addition of CHCl2OCH3 (0.58 g). The solution was stirred for another 15 min with ice-water bath, 30 min at RT, then 15 min at 35 C. Then the red solution was poured into ice and extract with dichloromethane. Workup and purification by chromatography (silicagel column, eluding with EtOAc/:hexane 1:4) gave 973 mg of 2,5-dimethoxy-3,4-dimethyl-benzaldehyde.
