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. 131747-62-1, name is 3-(Trifluoromethyl)pyridine-2-carboxaldehyde. A new synthetic method of this compound is introduced below., SDS of cas: 131747-62-1
To a solution of 185 (50 mg, 0.2808 mmol) in toluene 15 ml was added 66 (68.8 mg, 0.393 mmol). PTSA (106.7 mg, 0.561 mmol) was added to the reaction mass and stirred at 120 C. for 6 h. The reaction mass was diluted with ethyl acetate and washed with water (3×25 ml.). The organic layer was dried over sodium sulphate and concentrated to get the crude 189, which was used for next step without further purification.
