Reaction Steps

A mixture of 2-(2-methoxyphenyl)-3-pyridinamine (30.8 mg, 0.15 mmol), 4-chloro-5,7-difluoro-3-methyl-2-(2-pyridinyl)quinoline (67.8 mg, 0.23 mmol), 2-dicyclohexylphosphino-2,4,6,-triisopropylbiphenyl (15.5 mg, 0.03 mmol), tris(dibenzylideneacetone)dipalladium (0) (14.5 mg, 0.016 mmol), and sodium tert-butoxide (45.1 mg, 0.47 mmol) in dry toluene (2.0 mL) was degassed by nitrogen. The mixture was heated to 90° C. After 21.5 h, the reaction was cooled to rt, then treated with water. After extracting twice with EtOAc, the organic layers were combined and dried over anhydrous magnesium sulfate. After filtration and concentration the residue was purified on basic alumina (0-30% EtOAc in hexanes) to afford an light yellow solid as 5,7-difluoro-N-(2-(2-methoxyphenyl)-3-pyridinyl)-3-methyl-2-(2-pyridinyl)-4-quinolinamine. 1H NMR (400 MHz, CDCl3) δ ppm 8.67 (1H, m), 8.31 (1H, d, J=4.5 Hz), 7.82 (1H, m), 7.70 (1H, m), 7.54 (3H, m), 7.30 (1H, m), 7.18 (1H, m), 7.06 (2H, t, J=7.5 Hz), 7.01 (1H, m), 6.87 (1H, ddd, J=13.2, 8.7, 2.0 Hz), 3.86 (3H, s), 1.82 (3H, br. s.). Mass Spectrum (pos.) m/e: 455.2 (M+1).
