Method as described for intermediate 5 using (S)-ethyl 2-chloro-4-(3-methylmorpholino)-5H-pyrrolo[3,4-d]pyrimidine-6(7H)-carboxylate (intermediate 11) and 1-(4-(hydroxymethyl)phenyl)-3-(4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)urea as starting materials, and [1,1′-bis(diphenylphosphino)ferrocene]dichloropalladium(II) as catalyst. The reaction mixture was filtered through a celite 545 pre-packed cartridge (2.5 g), washed with MeOH and solvent removed in vacuo. The residue was purified first by prep HPLC (low pH) yielding the title compound (34 mg, 0.06 mmol, 41%).
