Reference of 13273-53-5, 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 13273-53-5 as follows.

General procedure: To a 50 mL round bottle flask was added 1,1?-Bis(diphenylphosphino)ferrocenedichloro Palladium(II) (0.1equiv), bromide (1.0equiv) and vinylboronic acid pinacol ester (2.0equiv) in 20mL dioxane. The mixture was degassed for 5min, and sodium carbonate aqueous solution (2.0M, 10equiv) was added. The mixture was then heated to 85C for 14h. After cooled to rt, the reaction mixture was filtered through a short Celite pad and washed with EtOAc. The organic solution was concentrated under reduced pressure and the residue was loaded into combi flush for purification to afford the product as oil.
