Application of 90145-48-5, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 90145-48-5, name is 5-Bromopyridine-2-carboxamide, molecular formula is C6H5BrN2O, The compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.
2-Benzothienylboronic acid (1.8 mmol), 5-bromopyridine-2-carboxamide (1.2 mmol), 2M K2CO3 (2.4 mL), Pd(dppf)Cl2 (0.12 mmol) were mixed and stirred at 80 C. in DMF for 3 h. The reaction mixture was filtered and to the filtrated was added EtOAc and H2O. The layers were separated and the aqueous phase was extracted twice with EtOAc. The organic extracts were dried over Na2SO4. The solvent was evaporated in vacuo to give a brown solid. The crude was subjected to reverse phase HPLC to afford the title compound as a light brown solid (11 mg). 1H NMR delta ppm 9.07 (d, 1H) 8.34 (dd, 1H) 8.24-8.02 (m, 5H) 7.73 (s br, 1H) 7.54-7.37 (m, 2H); MS m/z 255 (M+H).
While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 90145-48-5, 5-Bromopyridine-2-carboxamide.
