Reaction Steps

Prepared according to procedure Y by stirring 4-chloro-5,7-difluoro-3-methyl-2-(3-(trifluoromethyl)benzyl)quinoline (50 mg, 0.135 mmol), 4-(3,3-dimethyl-2,3-dihydro-1H-pyrrolo[3,2-b]pyridin-6-yl)morpholine (31.4 mg, 0.135 mmol), Pd2dba3 (12 mg, 0.013 mmol), XPhos (13 mg, 0.027 mmol), sodium tert-butoxide (39 mg, 0.404 mmol), and toluene (1.3 mL) at 100° C. for 30 min. Purification by reverse-phase HPLC (0-90% acetonitrile in water) gave 4-(3,3-dimethyl-6-(4-morpholinyl)-2,3-dihydro-1H-pyrrolo[3,2-b]pyridin-1-yl)-5,7-difluoro-3-methyl-2-(3-(trifluoromethyl)benzyl)quinoline. 1H NMR (400 MHz, chloroform-d) δ ppm 7.60-7.66 (1H, m), 7.40-7.55 (5H, m), 6.94-7.01 (1H, m), 5.53-5.56 (1H, m), 4.47 (2H, s), 3.78-3.85 (1H, m), 3.67-3.78 (4H, m), 3.57 (1H, d, J=8.8 Hz), 2.86-2.97 (4H, m), 2.22 (3H, s), 1.48-1.58 (3H, m), 1.46 (3H, s). Mass Spectrum (ESI) m/e=569.0 (M+1).
