Reaction Steps

A solution of EXAMPLE 7F (210 mg), potassium acetate (176 mg), 3-fluorobenzeneboronic acid (84 mg), and (1,1′-bis(diphenylphosphino)ferrocene)dichloropalladium (II) (12 mg) in DMF (6 mL) was heated at 90° C. for 3 hours then cooled, diluted with dichloromethane, washed with water, and dried (Na2SO4), filtered, and concentrated; and the concentrate was flash chromatographed on silica gel with 0-2% methanol/dichloromethane.
