실험 절차

To a solution of 2-(4-amino-5-bromo-pyrrolo[2,1-f][1,2,4]triazin-7-ylmethyl)-cyclopropanecarboxylic acid ethyl ester (1.33 g, 4 mmol) in degassed DMF (6.6 mL) was added 2-benzyl-6-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-2H-indazole (2.1 g, 6.3 mmol), Pd(PPh3)4, and 2N Na2CO3 solution (5.3 mL). The reaction was irradiated in a microwave reactor at 150° C. for 10 min. After cooling the mixture was partitioned between EtOAc and H2O. The organic phase was separated and dried over Na2SO4, filtered, and evaporated in vacuo. The crude was purified by Biotage® (50-100% EtOAc/hexane) to give the title product as an off white solid, 1.0 g (yield 54%). 1H NMR (300 MHz, DMSO-d6) δ 8.60 (s, 1 H), 8.05 (d, 2 H), 8.0 (s, 1 H), 7.90 (d, 1 H), 7.70 (s, 1 H), 7.60-7.40 (m, 7 H), 7.25 (d, 1 H), 7.20 (s, 1 H), 5.70 (s, 2 H), 4.0 (m, 2 H), 3.0 (m, 2 H), 1.70 (m, 2 H), 1.2-1.0 (m, 5 H); ES-MS m/z 5467.27 [M+H]+, HPLC RT (min) 2.79.
