(3aR,6aR)-5-Methyl-1-(4-(4,4,5,5-tetramethyl-1,3-dioxaborolan-2-yl)phenyl)octa-hydro-pyrrolo[3,4-b]pyrrole (50 mg, 0.15 mmol), 2-(5-bromopyridin-2-yl)pyridazin-3(2H)-one (42 mg, 0.17 mmol), Pd(PPh3)2Cl2 (11 mg, 0.01 mmol), 2-(dicyclohexylphosphino)biphenyl (5.6 mg, 0.016 mmol) and Na2CO3 (1M, 225 μL) were placed in a microwave tube, purged with N2 and a mixture of solvents (EtOH:dioxane=1:1, 1 mL) was added. The mixture was heated to 140° C. in a microwave reactor for 15 minutes, cooled to ambient temperature, was filtered, and concentrated under reduced pressure. The residue was purified via chromatography (SiO2, 0-10% MeOH in CH2Cl2) to provide the title compound, 1H NMR (300 MHz, CDCl3): δ=8.82 ppm (d, J=2.8 Hz, 1H), 7.98 (m, 2H), 7.73 (d, J=8.2 Hz, 1H), 7.52 (m, 2H), 7.28 (dd, J=10.1, 3.7 Hz, 1H), 7.09 (dd, J=10.1, 1.7 Hz, 1H), 6.67 (m, 2H), 4.39 (m, 1H), 3.66 (m, 1H), 3.30 (m, 3H), 2.87 (m, 2H), 2.59 (s(br), 3H), 2.23 (m, 2H), 2.05 (m, 1H). MS (ESI, M+1): 374.2.
