実験手順
Prepared in a manner similar to 1-methyl-3-phenyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-indazole, but using 6-bromo-1-methyl-1H-benzo[d][1,2,3]triazole instead of 5-bromo-1-methyl-3-phenyl-1H-indazole. 1H NMR (400 MHz, CDCl3) δ 8.04 (dd, J=6.8, 1.6 Hz, 2H), 7.79 (d, J=8.6 Hz, 1H), 4.33 (s, 3H), 1.39 (s, 12H).
