실험 절차
A mixture of 1-(6-chloro-1,7-naphthyridin-2-yl)cyclopentanol (65 mg, 0.26 mmol), cyclopropanecarboxamide (67 mg, 0.8 mmol), Chloro[2-(dicyclohexylphosphino)-3-,6-dimethoxy-2,4′-6′-tri-1-pr-1,1′-biphenyl)][2-(2-aminoethyl )Ph]Pd(II) (31 mg, 0.04 mmol), (dicyclohexylphosphino)-3-,6-dimethoxy-2,4′-6′-tri-i-pr-1,1′-biphenyl (21 mg, 0.04 mmol), and cesium carbonate (170 mg, 0.52 mmol) in 1,4-dioxane (1.5 mL) was heated at 90° C. for 1 hour. The cooled reaction mixture was diluted with ethyl acetate (50 mL) and washed with water (50 mL). The organic layer was separated, dried over sodium sulfate, filtered, and evaporated in vacuo to afford a residue that was purified by by reverse phase HPLC (5-85% acetonitrile in water with 0.1% formic acid over 14 min) to afford the title compound as an off-white solid (35 mg, 45%). 1H NMR (400 MHz, DMSO) δ 10.97 (s, 1H), 9.12 (s, 1H), 8.47 (s, 1H), 8.30 (d, J=8.8 Hz, 1H), 8.00 (d, J=8.8 Hz, 1H), 5.32 (s, 1H), 2.29-2.17 (m, 2H), 2.11-2.03 (m, 1H), 1.95-1.75 (m, 6H), 0.91-0.78 (m, 4H). LCMS (Method E): RT=3.811 min, M+H+=298.1.
