Procedure

(R)—N2-(1-phenylpropyl)-6-(quinolin-5-yl)pyrazine-2,3-diamine. (R)-6-Bromo-N2-(1-phenylpropyl)pyrazine-2,3-diamine (0.440 g, 1.43 mmol), quinoline-5-boronic acid (0.273 g, 1.58 mmol), tetrakis(triphenylphosphine)palladium (0.165 g, 0.143 mmol), potassium carbonate (0.789 g, 5.72 mmol), water (8 mL) and dimethylformamide (30 mL) were reacted according to General Procedure B. The crude was purified via Biotage silica gel chromatography (0-10% methanol/dichloromethane, 40S column) to afford the title compound (0.476 g, 93% yield). MS (ESI) m/z 356.4 [M+1]+.
