Electric Literature of 83766-88-5, In the chemical reaction process,reaction time,type of solvent,can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product.An updated downstream synthesis route of 83766-88-5 as follows.
Carboxylic acid (0.2 g, 1.64 mmol), tert-butoxypyridine (0.33 g, 2.21 mmol) and boron trifluoride diethyl etherate (0.31 g, 2.21 mmol) in dry PhCH3 (2 mL) were added to a 20-ml vial. The reaction mixture was then allowed to stir at room temperature for 30 min before quenching with anhydrous NaHCO3. The reaction mixture was diluted with ethyl acetate (30 mL), then washed with water (20 mL), followed by brine (20 mL). The organic layer was dried over anhydrous sodium sulfate and carefully concentrated under reduced pressure. The resulting residue was then purified by flash column chromatography on silica gel with 0:4 to 1:4 dichloromethane/hexane as eluent to yield the desired product 5a as a colorless oil.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,83766-88-5, its application will become more common.
