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. 3921-01-5, name is 2,4-Dibromopyrimidine, molecular formula is C4H2Br2N2, 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. Quality Control of 2,4-Dibromopyrimidine
2,4-dibromopyrimidine (438.4mg, 1.84mmol) and potassium carbonate (1.27g, 9.21mmol) in tetrahydrofuran (10mL) were added together and stirred at room temperature for 5min. Morpholine (174.8muL, 2.03mmol) was then added dropwise and the solution continued to stir at room temperature for 5h. The reaction mixture was filtered and the filtrate was collected and then concentrated under reduced pressure. The products were purified by silica column chromatography in hexanes and ethyl acetate to afford 28a and 28b in 19% and 66% yields, respectively. (0070) 4-(4-bromopyrimidin-2-yl)morpholine (28a). (White solid, Yield: 19%). 1H NMR (500MHz, CDCl3) delta ppm 3.74-3.77 (m, 4H) 3.79-3.83 (m, 4H) 6.70 (d, J=4.88Hz, 1H) 8.05 (d, J=4.88Hz, 1H). LCMS found 246.0, [M+H]+. (0071) 4-(2-bromopyrimidin-4-yl)morpholine (28b). (White solid, Yield: 66%) 1H NMR (500MHz, CDCl3) delta ppm 3.66 (br. s., 4H) 3.76-3.83 (m, 4H) 6.43 (d, J=6.35Hz, 1H) 8.02 (d, J=6.35Hz, 1H). LCMS found 246.0, [M+H]+.
With the rapid development of chemical substances, we look forward to future research findings about 3921-01-5.
