Procedure

A solution of (S)-tert-butyl 2-chloro-4-(3-methylmorpholino)-5H-pyrrolo[3,4-d]pyrimidine-6(7H)-carboxylate (intermediate 1) (214 mg, 0.603 mmol), 1-ethyl-3-(3-fluoro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)urea (intermediate 28) (211 mg, 0.685 mmol), [1,1′-Bis(diphenylphosphino)ferrocene]dichloropalladium (II), complex with dichloromethane (25 mg, 0.0306 mmol) and sodium carbonate (179 mg, 1.69 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 then at 130° C. for 15 minutes. The reaction mixture was concentrated in vacuo and the residue was re-dissolved in a mix of H2O and EtOAc. The aqueous phase was basified by the addition of aqueous NaOH and extracted into EtOAc. The organic extracts were combined, dried over magnesium sulphate and concentrated in vacuo. The sample was purified via preparative HPLC at low pH to yield the title compound (36 mg, 13%).
