Application of 107867-51-6, 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. 107867-51-6, name is 5-(Trifluoromethyl)pyridine-2,3-diamine, molecular formula is C6H6F3N3, 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.
To a mixed solution of 300 mg of 1- [3- (ethylsulfonyl) -6-iodoimidazo [1,2-a] pyridin-2-yl] ethan-1-one and 5 ml of dimethylsulfoxide was added 48 mass% 1 ml of hydrochloric acid was added.After completion of the addition, the reaction mixture was stirred at 80 C. for 2 hours. After completion of the stirring, 141 mg of 5- (trifluoromethyl) pyridine-2,3-diamine was added to the reaction mixture at room temperature.After the addition was completed, the reaction mixture was stirred at room temperature for 16 hours. After completion of the reaction, 10 ml of water was added to the reaction mixture at room temperature. After completion of the addition, sodium hydrogencarbonate was added to the reaction mixture for neutralization, followed by extraction with ethyl acetate (20 ml × 2).The obtained organic layer was dehydrated with anhydrous sodium sulfate and dried, and then the solvent was distilled off under reduced pressure. The precipitated solid was filtered off by filtration.The resulting solid was washed with diisopropyl ether to give the desired product 3- [3- (ethylsulfonyl) -6-iodoimidazo [1,2-a] pyridin-2-yl] – 7 – (trifluoromethyl ) Pyrido [2,3-b] pyrazine as a yellow solid.
While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 107867-51-6, 5-(Trifluoromethyl)pyridine-2,3-diamine.
