PROCEDURE
实验过程
A mixture of 6-bromo-2-furan-2-yl-[1,2,4]triazolo[1,5-a]pyrazin-8-ylamine (50 mg, 0.179; see Examples 1 and 2), 4-trifluoromethyl-phenyl boronic acid (0.196 mmol), Pd(dppf)Cl2 (7 mg, 0.009 mmol), and aqueous Na2CO3 (2 M, 330 μL) in DMF (2 mL) was degassed under N2 and then heated (at around 100° C.) for overnight. The reaction was filtered and then purified by HPLC (C18, H2O:MeCN gradient). 1H NMR (300 MHz, DMSO-d6) δ 6.77 (dd, J=3.4, 1.8 Hz, 1H), 7.19 (dd, J=3.4, 0.8 Hz, 1H), 7.70 (br. s, 2H), 7.87 (d, J=8.2 Hz, 2H), 7.93 (dd, J=1.8, 0.7 Hz, 1H), 8.31 (d, J=8.2 Hz, 2H), 8.8 (s, 1H). MS: m/z 346 [M+H]+.
