Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps,and cheap raw materials. 175277-33-5, name is 4-(Dimethoxymethyl)-2-methylpyrimidine. A new synthetic method of this compound is introduced below., COA of Formula: C8H12N2O2
4-Dimethoxymethyl-2-methyl-pyrimidine (4.5 g, 26.7 mmol) was added to a solution of HBr (48% in H2O, 10 niL) and stirred at room temperature for 2 hours. It was then diluted with water and washed with diethylether (2x). The aqueous layer was carefully neutralized with saturated sodium carbonate and extracted with ethyl acetate (2x). The combined extracts were dried over MgSO4. 2-Propanol (100 mL) was added. To this solution, aniline (2.5 mL, 26.7 mmol) was added and followed with diphenylphosphite (5.1 mL, 26.7 mmol). The reaction mixture was stirred at room temperature overnight and then concentrated. The residue was purified on silica gel column with 20% ethyl acetate/CH2Cl2 to give a yellow solid (3.3 g, 29% for 2 steps) as the desired product. MS (ESP+) m/z 432.2 (M + 1).
