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, 3,4-Difluoro-2-((2-fluoro-4-iodophenyl)amino)benzoic acid, other downstream synthetic routes, hurry up and to see.
Adding a certain compound to certain chemical reactions, such as: 391211-97-5, name is 3,4-Difluoro-2-((2-fluoro-4-iodophenyl)amino)benzoic acid, belongs to iodides-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 391211-97-5, COA of Formula: C13H7F3INO2
A solution of 3,4-difluoro-2-[(2-fluoro-4-iodophenyl)amino]benzoic acid (201 mg, 0.512 mmol), prepared using procedures similar to those described in US 7,019,033, 3-(2- aminopyrimidin-4-yl)azetidin-3-ol (87 mg, 0.52 mmol), benzotriazol-1-yl-oxy- tris(pyrrolidino)phosphonium hexafluorophosphate (293 mg, 0.563 mmol) and MN-diisopropylethylamine (270 uL, 2.82 mmol) in N,jV-dimethylformamide (2 mL) was stirred at room temperature for 2Oh. The mixture was partitioned between ethyl acetate and saturated sodium bicarbonate. The organic layer was separated and washed with brine, dried over sodium sulfate, filtered and the filtrate concentrated in vacuo. The residue was purified by reverse phase HPLC to afford the title compound 3-(2-aminopyrimidin-4-yl)-l-({3,4- difluoro-2-[(2-fluoro-4-iodophenyl)amino]phenyl}carbonyl)azetidin-3-ol (22 mg, 7%). 1H NMR (400 MHz, CD3OD): 8.23-8.20 (d, IH), 7.48-7.43 (d, IH), 7.35-7.32 (m, 2H), 7.09- 7.00 (m, IH), 6.88-6.84 (d, IH), 6.70-6.63 (t, IH), 4.59-4.54 (d, IH), 4.45-4.40 (d, IH), 4.23- 4.18 (d, IH), 3.04-3.99 (t, IH); MS (EI) for C20H15F3IN5O2: 542 (MH+).
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, 3,4-Difluoro-2-((2-fluoro-4-iodophenyl)amino)benzoic acid, other downstream synthetic routes, hurry up and to see.
