실험 절차
(R)-2-(3-Amino-6-(quinolin-5-yl)pyrazin-2-ylamino)-2-phenylethanol. (R)-2-(3-Amino-6-bromopyrazin-2-ylamino)-2-phenylethanol (0.700 g, 2.26 mmol), quinoline-5-boronic acid (0.431 g, 2.48 mmol), tetrakis(triphenylphosphine)-palladium (0.287 g, 0.226 mmol), potassium carbonate (1.24 g, 9.04 mmol), water (8 mL) and dimethylformamide (35 mL) were reacted according to General Procedure B. The crude material was purified via Biotage silica gel chromatography (40-100% ethyl acetate/hexanes, 40S column) to afford the title compound (0.546 g, 67% yield). MS (ESI) m/z 358.3 [M+1]+.
