実験手順

A solution of methyl 2-chloro-4-morpholino-5H-pyrrolo[3,4-d]pyrimidine-6(7H)-carboxylate (intermediate 25) (10 mg, 0.335 mol), 1-cyclopropyl-3-(3-fluoro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)urea (intermediate 29) (122 mg, 0.382 mmol), [1,1′-Bis(diphenylphosphino)ferrocene]dichloropalladium (II), complex with dichloromethane (14 mg, 0.0168 mmol) and sodium carbonate (107 mg, 1.01 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 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 low pH to yield the title compound (33 mg, 22%).
