Procedure

A solution of (S)-methyl 2-chloro-4-(3-methylmorpholino)-5H-pyrrolo[3,4-d]pyrimidine-6(7H)-carboxylate (intermediate 26) (98 mg, 0.313 mmol), 1-ethyl-3-(3-fluoro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)urea (intermediate 28) (110 mg, 0.357 mmol), [1,1′-Bis(diphenylphosphino)ferrocene]dichloropalladium (II), complex with dichloromethane (13 mg, 0.0157 mmol) and sodium carbonate (93 mg, 0.876 mmol) in 2 ml of a 7:3:1 mixture of DME:H2O:EtOH respectively was heated in the microwave at 115° C. for 45 minutes. The reaction was concentrated in vacuo and the residue was re-dissolved in a mix of H2O and EtOAc. The aqueous phase was extracted into EtOAc and the organic extracts were combined and concentrated in vacuo. The sample was then purified via preparative HPLC at low pH and then triturated in MeOH and filtered to yield the title compound (6 mg, 4%).
