2734-70-5, name is 2,6-Dimethoxyaniline, belongs to ethers-buliding-blocks compound, is considered to be a conventional heterocyclic compound, which is widely used in drug synthesis. The chemical synthesis route is as follows. Recommanded Product: 2734-70-5
Equipped with a mechanical stirrer, a condenser and a nitrogen gas through the mouth of the three-necked flask, were added 61.28g (0.40mol) 2,6- dimethoxy aniline and 135.00mL distilled water, stir under a nitrogen atmosphere.40.50mL slowly added dropwise concentrated hydrochloric acid (37percent mass fraction), the temperature of the system was maintained at 35 , then portionwise added 28.14g (0.21mol) 3,5- dimethylbenzaldehyde.System under reflux with vigorous stirring After 6h, the reaction system temperature was lowered to 50 , added in portions with stirring 16.40g sodium hydroxide powder.The solution was subjected to steam distillation, after suction filtration to obtain a solid powder.A solid powder with hot water, and dried dioxane was recrystallized, and dried to give alpha, alpha- bis (4-amino-3,5-dimethoxyphenyl) -1- (3 ‘, 5’-A phenyl) methane solid powder 77.56g (92percent yield)
The synthetic route of 2734-70-5 has been constantly updated, and we look forward to future research findings.
