uses | 2,3,4,5-tetramethoxytoluene is a very important pharmaceutical and chemical intermediate, mainly used to synthesize raw materials of coenzyme q series products (Q0 ~ 10). |
preparation | 4-methylguaiacol is used as the starting material, and the intermediates are obtained by dibromination 2, 3-dibromo-6-methoxy-4-methylphenol and 2, 5-dibromo-6-methoxy-4-methylphenol; then after alkylation, 4,5- dimethoxy -2, 3-dibromo-toluene and 4, 5-dimethoxy-3, 6-dibromo-toluene; finally, 2,3,4, 5-tetramethoxytoluene is obtained by methyl oxidation. |
