Procedure

A mixture of 2,5-bis(3,6-dihydro-2H-pyran-4-yl)pyridin-3-amine (47.3 mg, 0.18 mmol), 4-chloro-5,7-difluoro-3-methyl-2-(pyridin-2-yl)quinoline (47.8 mg, 0.16 mmol), 2-dicyclohexylphosphino-2,4,6,-triisopropylbiphenyl, (X-Phos) (12.6 mg, 0.026 mmol), tris(dibenzylideneacetone)dipalladium (0) (7 mg, 7.6 μmol), and sodium tert-butoxide (56.6 mg, 0.59 mmol) in dry toluene (1.5 mL) was degassed by nitrogen. The resulting reaction was heated to 90° C. and monitored with TLC and LC-MS. After 21 h, the reaction was cooled to rt then poured into water. After extracting twice with EtOAc and twice with DCM, the combined organic extractions were dried over anhydrous magnesium sulfate. After filtration and concentration, the residue was purified on basic alumina (10-30% EtOAc in hexanes) to afford a yellow solid as N-(2,5-bis(3,6-dihydro-2H-pyran-4-yl)-pyridin-3-yl)-5,7-difluoro-3-methyl-2-(pyridin-2-yl)quinolin-4-amine. 1H NMR (500 MHz, CDCl3) δ ppm 8.71 (1H, dt, J=4.9, 1.2 Hz), 8.27 (1H, d, J=1.7 Hz), 7.96 (2H, m), 7.66 (1H, m), 7.44 (1H, m), 7.32 (1H, d, J=10.3 Hz), 7.03 (2H, ddd, J=13.4, 8.6, 2.4 Hz), 6.37 (1H, m), 6.19 (1H, m), 4.40 (2H, m), 4.30 (2H, q, J=2.7 Hz), 4.04 (2H, t, J=5.4 Hz), 3.90 (2H, t, J=5.5 Hz), 2.72 (2H, m), 2.45 (2H, m), 2.18 (3H, s). Mass Spectrum (pos.) m/e: 513.1 (M+1).
