Adding a certain compound to certain chemical reactions, such as: 134363-45-4, 2-(Pyridin-3-yl)benzoic acid, 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, HPLC of Formula: C12H9NO2, blongs to pyridine-derivatives compound. HPLC of Formula: C12H9NO2
To a solution of 4-(4-Amino-2-fluoro-phenyl)-piperazine-1 -carboxylic acid te/t-butyl ester (1.00 g, 3.4 mmol) and 2-pyhd-3-yl benzoic acid (0.70 g, 3.7 mmol) in DMF (10 ml_) was added HATU (1.42 g, 3.7 mmol) and diisopropylamine (0.65 ml_, 3.7 mmol). After stirring at room tempertaure for 18 h, the reaction mixture was diluted with EtOAc (100 ml_) and washed with H2O (4×50 ml_). The organic extracts were combined, dried (Na2SO4), and the solvent was evaporated under reduced pressure. Chromatography of the resulting residue (SiO2: EtOAc:Hex) yielded 4-[2-fluoro-4-(2-pyridin-3-yl- benzoylamino)-phenyl]-piperazine-1 -carboxylic acid te/t-butyl ester which was further dissolved in MeOH (20 ml_) and 4N HCI in dioxanes. After stirring for 5 h, the reaction mixture was concentrated down, neutralized with 1 N NaOH, and extracted with EtOAc (3x75ml_). The organic extracts were combined, dried (Na2SO4), and the solvent was evaporated under reduced pressure to yield the title compound.MS: mass calcd. for C22H21FN4O, 376.17; m/z found, 378.4 [M+H]+
The synthetic route of 134363-45-4 has been constantly updated, and we look forward to future research findings.
