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. 16019-33-3, name is 2-(4,6-Dichloropyrimidin-5-yl)acetaldehyde, molecular formula is C6H4Cl2N2O, 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. Formula: C6H4Cl2N2O

Step 1: Synthesis of 7-(tert-butyl)-4-chloro-7H-pyrrolo[2,3-d]pyrimidine A mixture solution of 29.3 g of 2-(4,6-dichloropyrimidin-5-yl)acetaldehyde, 13.4 g of tert-butylamine, and 29.7 g of N,N-diisopropylethylamine in 200 mL of ethanol was stirred with heating under reflux for 2 hours. After cooling, the reaction mixture was concentrated. The residue was diluted with ethyl acetate, washed with water and subsequently washed with a saturated aqueous sodium chloride solution. The obtained organic layer was dried over anhydrous sodium sulfate, filtered, and concentrated. The obtained residue was purified by silica gel chromatography, thereby obtaining 21.5 g of the title compound. Physical Properties: m/z [M+H]+ 210.0.
