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. 1124-29-4, name is 5-Acetylpyridin-2(1H)-one, molecular formula is C7H7NO2, 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. HPLC of Formula: C7H7NO2
General procedure: [0561] To a solution of III-3 (1 eq.) in DCM (0.1 mmol/mL) was added boronic acid III-4 (2 eq.), Cu(OAc)2 (1 eq), Pyridine (10 eq.) and Pyridine-N-Oxide (2 eq.), followed by addition of 4 molecular sieve (quantity approx. equal to III-3). The reaction mixture was stirred at rt under oxygen atmosphere overnight. After completion of the reaction indicated by TLC, the resulting mixture was filtered and washed with, the filtrate was washed with brine, dried over Na2SO4 and concentrated. The residue was purified by column chromatography on silica gel to give III-5. [0562] Compound 10 (61% yield): 1H NMR (DMSO-d6, 400 MHz) delta 8.43 (d, J=2.4 Hz, 1H), 7.90 (dd, J=9.6, 2.4 Hz, 1H), 7.39 (d, J=8.8 Hz, 2H), 7.06 (d, J=8.8 Hz, 2H), 6.51 (d, J=9.6 Hz, 1H), 3.81 (s, 3H), 2.41 (s, 3H).
With the rapid development of chemical substances, we look forward to future research findings about 1124-29-4.
