反応手順
(S)-2-(3-Amino-6-(quinolin-5-yl)pyrazin-2-ylamino)-2-phenylethanol. (S)-2-(3-Amino-6-bromopyrazin-2-ylamino)-2-phenylethanol (0.882 g, 2.26 mmol), quinoline-5-boronic acid (0.544 g, 2.48 mmol) tetrakis(triphenylphosphine)-palladium (0.331 g, 0.287 mmol), potassium carbonate (1.25 g, 9.08 mmol), water (8 mL) and dimethylformamide (30 mL) were reacted according to General Procedure B. The crude material was purified via Biotage silica gel chromatography (0-10% methanol/dichloromethane, 40S column) to afford the title compound (0.524 g, 51% yield). MS (ESI) m/z 358.3 [M+1]+.
