Application of 36953-37-4, 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. 36953-37-4, name is 4-Bromopyridin-2(1H)-one, molecular formula is C5H4BrNO, 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.
To a solution of sodium 2-chloro-2,2-difluoroacetate (12.38 g, 81 mmol) in MeCN (400 mL) was added 4-bromopyridin-2(1H)-one (10.09 g, 58 mmol) and the reaction was refluxed for 20 h. The mixture was filtered and the solid purified by chromatography on silica gel (80 g column, 0-10% EtOAc/isohexane) to afford the title compound (6.75 g, 51%) as a clear colourless liquid.1H NMR (DMSO-d6) d 8.10 (d, J = 5.5 Hz, 1H), 7.86-7.52 (m, 2H), 7.49 (d, J = 1.6 Hz, 1H).
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 36953-37-4, 4-Bromopyridin-2(1H)-one.
