1,1′ Bis(diphenylphosphino)ferrocnee]dichloropalladium(II),w/DCM (0.033 g, 0.040 mmol) was added to a solution containing 2-bromobenzo[4,5]imidazo[1,2-a]pyrimidine (0.2 g, 0.806 mmol), tert-butyl (2-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)carbamate (0.386 g, 1.209 mmol), Copper(I) iodide (0.015 g, 0.081 mmol), and Potassium carbonate (0.806 ml, 1.612 mmol) in DMF. The solution was heated in the microwave for 15 minutes at 120° C. The reaction was cooled to room temperature. Diluted with water, extracted with ethyl acetate, combined organics, dried, filtered and concentrated. Purified by Combiflash column using 0% to 80% ethyl acetate in hexanes to afford tert-butyl (2-(benzo[4,5]imidazo[1,2-a]pyrimidin-2-yl)phenyl)carbamate (0.13 g, 0.361 mmol, 44.7% yield).
