Electric Literature of 4595-59-9, 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 4595-59-9 as follows.

General procedure: In the reaction tube with a magnetic bar was added the solution of aryl bromides (0.5 mmol) and phenylboronic acid (91 mg, 0.75 mmol), NaOH (24 mg, 0.6 mmol), complex 1 (0.0001-0.02 mol%, dissolved in DMA) and ethanol (3 mL). After stirred for the required time in the preset conditions, the reaction mixture was cooled to room temperature, and then quenched by 1 mL brine and 3 mL water, and extracted with ethyl acetate (3×5 mL). The combined organic layer was dried over anhydrous MgSO4 and the filtrate was concentrated to dryness under reduced pressure. The crude products were purified by column chromatography (petroleum ether, ethyl acetate) on silica gel.

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,4595-59-9, its application will become more common.
