실험 절차

A solution of (S)-1-(2-chloro-4-(3-methylmorpholino)-5H-pyrrolo[3,4-d]pyrimidin-6(7H)-yl)ethanone (intermediate 24) (99 mg, 0.334 mmol), 1-ethyl-3-(3-fluoro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)urea (intermediate 28) (103 mg, 0.334 mmol), [1,1′-Bis(diphenylphosphino)ferrocene]dichloropalladium (II), complex with dichloromethane (14 mg, 0.0167 mmol) and sodium carbonate (99 mg, 0.934 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 basified by the addition of aqueous NaOH and extracted into EtOAc. The organic extracts were combined and concentrated in vacuo. The sample was purified via preparative HPLC at low pH, and then at high pH, to yield the title compound (6 mg, 4%).
