Participants

Reaction Steps

(3-Amino-6-(5-quinolyl)pyrazin-2-yl)[(4-methoxyphenyl)methyl]amine. 6-Bromo-N2-(4-methoxybenzyl)pyrazine-2,3-diamine (0.928 g, 3.00 mmol), quinoline-5-boronic acid (0.675 g, 3.9 mmol), tetrakis(triphenylphosphine)palladium (0.306 g, 0.265 mmol), potassium carbonate (1.10 g, 7.95 mmol), water (7 ml) and dimethylformamide (35 mL) were reacted according to General Procedure B. The crude material was purified via Biotage silica gel chromatography (0-10% methanol in dichloromethane) followed by triturating with water/methanol to afford the title compound (0.165 g, 15% yield). MS (ESI) m/z 358.3 [M+1]+.
