Reference of 25081-39-4,Some common heterocyclic compound, 25081-39-4, name is Methyl 3,5-dimethylbenzoate, molecular formula is C10H12O2, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
3.71 g (0.0304 mol) of 2,4-dimethylphenol was dissolved in 111.40 g of toluene,Then 0.22g (0.00304mol) of n-butylamine was added and reacted at 110 C for 4h.Add 5.00g (0.0304mol) to the reaction solutionMethyl 3,5-dimethylbenzoate,Incubation reaction for 6h;After the reaction solution was cooled to 50 C, the pH of the reaction solution was adjusted to 6-7 with 5 wt% H2SO4.Then the reaction solution was washed three times with 30 mL of water, and toluene was distilled off under reduced pressure.The residue in the kettle was recrystallized with 100 mL of methanol.Gives a white solid,The target product yield was 80%.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route Methyl 3,5-dimethylbenzoate, its application will become more common.
