Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 52548-63-7, name is 5-Fluoro-2-iodobenzoic acid, A new synthetic method of this compound is introduced below., SDS of cas: 52548-63-7
To a solution of 5-fluoro-2-iodo- benzoic acid (3.86 g, 14.65 mmol), 2H-[1 ,2,3]triazole (2.5 g, 36.2 mmol),Cs2CO3 (8.62 g, 24.5 mmol), trans-N, N’-dimethyl-cyclohexane-1 ,2-diamine (0.4 ml_), Cul (244 mg) and DMF (13 ml_) were added to a microwave ready vessel and heated to 100 C for 10 min. The mixture was cooled, diluted with water, and extracted with EtOAc. The aqueous layer was acidified and extracted with EtOAc. The organic layer was dried over Na2SO and concentrated. The residue was purified by FCC (SiO2, gradient DCM to 10% MeOH/1 %HOAc/DCM) gave the product as a white powder, (2.14 g, 71 %). 1H NMR (400 MHz, CD3OD): 7.91 (s, 2H), 7.76 (dd, J = 8.9, 4.8 Hz, 1 H), 7.59 (dd, J = 8.5, 2.9 Hz, 1 H), 7.49 – 7.42 (m, 1 H).; Intermediate 53: 2-[1 ,2,3]Triazol-1 -yl-benzoic acid.The title compound was isolated from the synthesis of Intermediate 13. 1H NMR (400 MHz, CD3OD): 6.70 (d, J = 0.9 Hz, 1 H), 6.50 (dd, J = 7.7, 1 .5 Hz, 1 H), 6.30 (d, J = 1 .0 Hz, 1 H), 6.24.6.18 (m, 1 H), 6.17 -6.1 1 (m, 1 H), 6.01 (dd, J = 7.8, 1 .0 Hz, 1 H).
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
