Procedure

A solution of (S)-ethyl 2-chloro-4-(3-methylmorpholino)-5H-pyrrolo[3,4-d]pyrimidine-6(7H)-carboxylate (intermediate 11) (100 mg, 0.31 mmol), 1-(3-fluoro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)-3-(2-fluoroethyl)urea (intermediate 31) (450 mg, 1.38 mmol), [1,1′-Bis(diphenylphosphino)ferrocene]dichloropalladium (II), complex with dichloromethane (16 mg, 0.02 mmol) and sodium carbonate (49 mg, 0.46 mmol) in 2 ml of a 7:3:2 mixture of DME:EtOH:H2O respectively was heated in the microwave at 130° C. for 1 hour. The reaction was filtered through celite and purified via preparative HPLC at high pH then low pH to yield the title compound (15 mg, 10%).

Workup
