Prepared according to procedure N using 2-(2,5-difluorophenyl)-7-fluoro-4-(6-iodo-3,3-dimethylindolin-1-yl)-3-methylquinoline (166 mg, 0.31 mmol) (described herein), morpholine (53.1 μL, 0.61 mmol), Pd2dba3 (41.9 mg, 0.046 mmol), dicyclohexyl(2′,4′,6′-triisopropylbiphenyl-2-yl)phosphine (43.6 mg, 0.091 mmol), and sodium 2-methylpropan-2-olate (88 mg, 0.915 mmol) in toluene (3.0 mL). The reaction mixture was stirred at 105° C. for 1 h. Purification afforded 2-(2,5-difluorophenyl)-4-(3,3-dimethyl-6-(4-morpholinyl)-2,3-dihydro-1H-indol-1-yl)-7-fluoro-3-methylquinoline as a yellow oil. 1H NMR (500 MHz, chloroform-d) δ ppm 7.88-7.99 (1H, m), 7.76-7.84 (1H, m), 7.27-7.35 (2H, m), 7.16 (2H, m), 7.09 (1H, d, J=8.1 Hz), 6.30-6.38 (1H, d), 5.57-5.69 (1H, s), 3.75 (6H, m), 2.98 (4H, d, J=2.4 Hz), 2.18 (3H, s), 1.52 (3H, s), 1.46 (3H, s). Mass Spectrum (ESI) m/e=504 (M+1).
