A mixture of 2-bromo-3-methylbenzonitrile (0.744 g, 3.79 mmol), N-(4-methoxybenzyl)-3-(tetrahydro-2H-pyran-4-yl)-6-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)quinolin-2-amine (0.60 g, 1.265 mmol), 2-(dicyclohexylphosphino)-2′,4′,6′,-tri-1-propyl-1,1′-biphenyl (0.121 g, 0.253 mmol), potassium phosphate, anhydrous (0.524 mL, 6.32 mmol), and Pd2(dba)3 (0.116 g, 0.126 mmol) was purged with N2 followed by the addition of degassed dioxane (2 mL) and degassed water (1.0 mL). The resulting mixture was heated in microwave at 140° C. for 12 min. The reaction went to completion and it was filtered, concentrated, and chromatographed on silica gel using gradient 2:1 hexanes/EtOAc to afford a yellow solid as (2-(2-(4-methoxybenzylamino)-3-(tetrahydro-2H-pyran-4-yl) quinolin-6-yl)-3-methylbenzonitrile.
