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-hydroxyethyl)urea (intermediate 32) (149 mg, 0.46 mmol), [1,1′-Bis(diphenylphosphino)ferrocene]dichloropalladium (II), complex with dichloromethane (15 mg, 0.018 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 concentrated in vacuo and the residue redissolved in a mix of MeOH/DCM. It was loaded onto an SCX cartridge and washed with two column volumes of MeOH/DCM before being eluted with 2M NH3 in MeOH and concentrated in vacuo. The sample was then purified via preparative HPLC at high pH to yield the title compound (32.8 mg, 22%).
