Adding a certain compound to certain chemical reactions, such as: 387-48-4, name is 3-Fluoro-2-iodobenzoic 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 387-48-4, HPLC of Formula: C7H4FIO2
Intermediate 93: 3-Fluoro-2-(1 H-pyrazol-1 -yl)benzoic acid.3-Fluoro-2-(1 H-pyrazol-1 -yl)benzoic acid. To a mixture of 3-fluoro-2- iodobenzoic acid (1 .4 g, 5.26 mmol), 1 H-pyrazole (0.72 g, 10.5 mmol), trans- N,N’-dimethyl-cyclohexane-1 ,2-diamine (0.17 mL, 1 .05 mmol), Cul (50.1 mg, 0.26 mmol), dioxane (50 mL) and water (0.028 mL) was added Cs2C03 (3.43 g, 10.5 mmol). The reaction mixture was heated to 100 C for 1 h. The reaction mixture was cooled to ambient temperature then diluted with water. The aqueous layer was acidified to pH2 and extracted with EtOAc (30 mL) three times. The organic layers were combined, dried over Na2S04, filtered and concentrated. Purification (FCC), (DCM to 10% MeOH/1 %HOAC/DCM) afforded the title compound as a colorless oil (790 mg, 72%). 1H NMR (400 MHz, CDCIs): 7.85 – 7.73 (m, 1 H), 7.54 – 7.44 (m, 1 H), 7.44 – 7.34 (m, 1 H), 6.55 (s, 1 H).
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-Fluoro-2-iodobenzoic acid, other downstream synthetic routes, hurry up and to see.
