3-Morpholino-6-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)quinolin-2-amine (0.15 g, 0.422 mmol, prepared as Example 2, Step 1-2), cyclopentyl 2-bromo-3-methylbenzoate (0.133 g, 0.470 mmol), potassium acetate (0.079 mL, 1.267 mmol), 2-dicyclohexylphosphino-2′,4′,6′,-triisopropylbiphenyl (0.020 g, 0.042 mmol), palladium(II) acetate (4.74 mg, 0.021 mmol), water (0.3 mL) and ethanol (2 mL) were combined in a microwave vial and heated to 145° C. for 30 min. The crude material was partitioned between water (40 mL) and DCM (50 mL). The organic layer was dried on magnesium sulfate, filtered and concentrated. The crude material was purified by silica chromatography (0-10% methanol in DCM gradient) to give cyclopentyl 2-(2-amino-3-morpholinoquinolin-6-yl)-3-methylbenzoate. MS (ESI, pos. ion) m/z: 432 (M+1).
