5-Methyl-N2-((R)-1-phenylethyl)-6-(quinolin-5-yl)pyrazine-2,3-diamine. (R)-6-Bromo-5-methyl-N2-(1-phenylethyl)pyrazine-2,3-diamine (0.534 g, 1.74 mmol), quinoline-5-boronic acid (0.331 g, 1.91 mmol), tetrakis(triphenylphosphine) palladium (0.20 g, 0.175 mmol), and potassium carbonate (0.96 g, 6.96 mmol) in water (4 mL) and dimethylformamide (15 mL) was reacted according to General Procedure B and purified via Biotage silica gel chromatography (0-10% methanol in dichloromethane, 40M column) and the resultant solid triturated with water/methanol to afford the title compound (0.42 g, 67% yield). MS (ESI) m/z 356.4 [M+1]+.
