Electric Literature of 32779-36-5, 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. 32779-36-5, name is 5-Bromo-2-chloropyrimidine, molecular formula is C4H2BrClN2, 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 5-bromo-2-chloropyrimidine (3 g, 15.50 mmol) in acetonitrile (40 mL) was added morpholine (4.1 mL, 47 mmol) and potassium carbonate (11 g, 78.80 mmol) . The mixture was heated at 85 and stirred for 10 h. The reaction mixture was cooled to rt and concentrated in vacuo. The residue was diluted with water (30 mL) . The resulting mixture was extracted with DCM (40 mL × 3) . The combined organic layers were dried over anhydrous Na2SO4and concentrated in vacuo to give a white solid product (3.6 g, 95) .[1814]MS (ESI, pos. ion) m/z: 245.9 [M+1]+.
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 32779-36-5, 5-Bromo-2-chloropyrimidine.
