Yield: 70%

Reaction Conditions:

with (1,1'-bis(diphenylphosphino)ferrocene)palladium(II) dichloride;potassium acetate in 1,4-dioxane at 90; for 12 h;Inert atmosphere;Miyaura Borylation Reaction;

Steps:

4.3. General methods for intermediates 6 and 10
General procedure: To a solution of borate (1 equiv) and bipinacol borate (1.2 equiv)in anhydrous dioxane, KOAc (3 equiv) and Pd(dppf)Cl2 (0.05% mol)were added. After reaction at 90 C for 12 h under N2 atmosphere,the solvent was concentrated and water was added to the reactionflask, and then the filter cake was washed with petroleum etherand acetonitrile to obtain the intermediates 6 and 10.
