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. 16063-70-0, name is 2,3,5-Trichloropyridine. A new synthetic method of this compound is introduced below., Product Details of 16063-70-0
23.7 g of the above product, 20 g of TCP, 15 g of anhydrous potassium carbonate, and 22 ml of dimethyl sulfoxide were mixed and stirred at 120 C for 4 h.After the reaction mixture was cooled, water and benzene were layered, and the organic phase was separated and washed with 1N aqueous sodium hydroxide.After drying over anhydrous sodium sulfate, the solvent was evaporated under reduced pressure to give a pale yellow crystalline solid.Recrystallization from n-hexane-ethyl acetate gave a white crystalline solid.M.p. 105.5-107 C, the total yield was 50.1%.
