実験手順

To a solution of (S)-4-(2-chloro-6-(cyclopropylmethyl)-6,7-dihydro-5H-pyrrolo[3,4-d]pyrimidin-4-yl)-3-methylmorpholine (intermediate 8) (50 mg, 0.16 mmol) and 1-methyl-3-(4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)urea (407 mg, 0.39 mmol) in DME/EtOH/H2O (7:3:2) (5 mL) was added Pd(PPh3)2(Cl)2 (7 mg, 0.008 mmol) and Na2CO3 (26 mg, 0.24 mmol). The reaction mixture was then heated by microwave at 130° C. for 30 minutes. The crude reaction mixture was then partitioned between water and EtOAc, the organic layer recovered, dried over MgSO4, filtered and the solvent removed in vacuo. The residue was purified by prep. LCMS (low pH). The solvent was removed in vacuo. The residue was then re-purified by Flash SCX2 column chromatography, affording the title compound as a white solid (34.8 mg, 51% yield).
