To a 10-mL microwave tube were added 6-bromo-1-cyclopentyl-N-[(4,6-dimethyl-2-oxo-1,2-dihydro-3-pyridinyl)methyl]-1H-indazole-4-carboxamide (70 mg, 0.158 mmol), cyclopropanesulfinic acid (40.8 mg, 0.316 mmol), dimethyl sulfoxide (3 mL), N,N′-dimethyl-1,2-ethanediamine methyl[2-(methylamino)ethyl]amine (55.7 mg, 0.632 mmol), and copper(II) trifluoromethanesulfonate (57.1 mg, 0.158 mmol), and the mixture was degassed for 5 min by bubbling nitrogen. The tube was sealed and the mixture irradiated at 120° C. (microwave) for 3 h. The mixture was filtered and the DMSO solution was purified using reverse-phase HPLC to give 45 mg of product. The product was collected as an off-white solid. 1H NMR (400 MHz, DMSO-d6) δ ppm 1.00-1.12 (m, 2H), 1.15-1.31 (m, 2H), 1.67-1.79 (m, 2H), 1.84-1.94 (m, 2H), 1.96-2.08 (m, 2H), 2.12-2.28 (m, 8H), 2.93-3.05 (m, 1H), 4.38 (d, J=5.05 Hz, 2H), 5.43 (quin, J=7.01 Hz, 1H), 5.90 (s, 1H), 8.01 (d, J=1.26 Hz, 1H), 8.44 (s, 1H), 8.52 (s, 1H), 8.83 (t, J=4.93 Hz, 1H), 11.57 (s, 1H); LCMS: (M+H)+=469.0
