Electric Literature of 106614-28-2, The chemical industry reduces the impact on the environment during synthesis 106614-28-2, name is Methyl 2,4-difluorobenzoate, I believe this compound will play a more active role in future production and life.
To a mixture of methyl 2,4-difluoro benzoate (1.0 g) in 1,4-dioxane (20 mL), 5-hydroxypyrrolo[2,3-b]pyridine (779 mg) and K3P04 (1.47 g) were added at 34C and heated to90C. The reaction mixture is stirred at the same temperature for 23 hours. K3P04 (396mg) was added at 90C to the reaction mixture and stirred for another 24 hours at thesame temperature. Cooled the reaction mixture to 32C and filtered on a celite bed.Washed the celite bed with ethyl acetate (20 mL) and evaporated the solvent in the filtrateto obtain crude product. The crude product was purified by column chromatography using60-120 silica gel mesh and 10-50% ethyl acetate- hexane as eluent to obtain the titlecompound as white solid. Yield: 588 mg; Purity by HPLC: 98.73%
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, Methyl 2,4-difluorobenzoate, other downstream synthetic routes, hurry up and to see.
