실험 절차

To a 30 mL microwave vial were added (R)-6-bromo-1-(sec-butyl)-N-((4,6-dimethyl-2-oxo-1,2-dihydropyridin-3-yl)methyl)-3-methyl-1H-indole-4-carboxamide (100 mg, 0.225 mmol), 1-(5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridin-2-yl)piperazine (85 mg, 0.293 mmol), 1,2-Dimethoxyethane (DME) (3 mL), water (1.000 mL) and sodium carbonate (0.338 mL, 0.675 mmol), and the mixture was degassed for 5 min by bubbling nitrogen. PdCl2(dppf)-CH2Cl2 adduct (14.70 mg, 0.018 mmol) was added and the tube was sealed. The mixture was irradiated (microwave) at 140° C. for 10 min. The mixture was concentrated and the residue was taken up into MeOH and filtered. The filtrate was purified using reverse-phase HPLC (eluent: 25% ACN/H2O, 0.1% NH4OH to 60% ACN/H2O, 0.1% NH4OH) to give 90 mg of product as off-white solid. 1H NMR (400 MHz, DMSO-d6) δ ppm 0.73 (m, 3H), 1.41 (d, J=6.57 Hz, 3H), 1.81 (td, J=7.14, 2.91 Hz, 2H), 2.11 (s, 3H), 2.15-2.20 (m, 3H), 2.24 (s, 3H), 2.77-2.83 (m, 4H), 3.41-3.49 (m, 4H), 4.35 (d, J=5.05 Hz, 2H), 4.54-4.68 (m, 1H), 5.87 (s, 1H), 6.88 (d, J=8.84 Hz, 1H), 7.17 (d, J=1.52 Hz, 1H), 7.26 (s, 1H), 7.73 (d, J=1.26 Hz, 1H), 7.91 (dd, J=8.84, 2.53 Hz, 1H), 8.16 (t, J=5.05 Hz, 1H), 8.50 (d, J=2.27 Hz, 1H); LCMS: 527.7 (MH+).
