A solution of (S)-4-(2-chloro-6-isopropyl-6,7-dihydro-5H-pyrrolo[3,4-d]pyrimidin-4-yl)-3-methylmorpholine (intermediate 22) (120 mg, 0.404 mmol), 1-(3-fluoro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)-3-(2-fluoroethyl)urea (intermediate 31) (145 mg, 0.445 mmol), [1,1′-Bis(diphenylphosphino)ferrocene]dichloropalladium (II), complex with dichloromethane (16 mg, 0.02 mmol) and sodium carbonate (128 mg, 1.21 mmol) in 2 ml of a 7:3:1 mixture of DME:H2O:EtOH respectively was heated in the microwave at 140° C. for 1 hour. The reaction was filtered through celite and purified via preparative HPLC at high pH to yield the title compound (15 mg, 8%).
