To a mixture of potassium phosphate (5.98 g, 28.2 mmol), dicyclohexyl(2′,4′,6′-triisopropylbiphenyl-2-yl)phosphine (0.54 g, 1.13 mmol), Pd2(dba)3 (0.26 g, 0.28 mmol), 2-bromo-3-methylbenzonitrile (2.21 g, 11.26 mmol) and 3-morpholino-6-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)quinolin-2-amine (2.00 g, 5.63 mmol, prepared as in Example 2, Step 1-2) was added dioxane (50.0 mL) and water (25.0 mL). The mixture was heated to 140° C. for 10 min. The reaction mixture was allowed to cool to RT, filtered and then partitioned between EtOAc and water. The organic layer was washed with water and brine, and concentrated. The residue was diluted with EtOAc and then filtered. The solid was dried in air to afford 2-(2-amino-3-morpholinoquinolin-6-yl)-3-methylbenzonitrile as a light brown solid.
