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. 22536-63-6, name is 2-Chloro-4-methoxypyrimidine, molecular formula is C5H5ClN2O, 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. COA of Formula: C5H5ClN2O
(1) Under an argon atmosphere, sodium hydride (100 mg) was added to a solution of 4-iodoaniline (220 mg) and 2-chloro-4-methoxypyrimidine (145 mg) in anhydrous DMF (10 ml), and the resulting mixture was stirred at 125C for 21 hours. The reaction solution was cooled to room temperature and water was added thereto, followed by extracting the resulting mixture with ethyl acetate. Organic layer was washed twice with water and once with saturated brine, and dried over anhydrous sodium sulfate. After removing anhydrous sodium sulfate by filtration, the filtrate was concentrated. The residue was purified by column chromatography (silica gel, eluent: hexane/ethyl acetate =10/1) to obtain N-(4-iodophenyl)-4-methoxypyrimidin-2-amine (46 mg).
With the rapid development of chemical substances, we look forward to future research findings about 22536-63-6.
