実験手順

To a solution of 5-(2-benzyl-2H-indazol-6-yl)-7-(4-piperazin-1-ylphenyl)pyrrolo[2,1-f][1,2,4]triazin-4-amine (100 mg, 0.20 mmol) in dichloromethane (2 mL) was added pyridine (23 μL, 0.28 mmol) followed by acetyl chloride (17 μL, 0.24 mmol). The mixture was stirred (rt) overnight. The mixture was diluted with dichloromethane (25 mL) and was washed with H2O (20 mL), brine, and was dried (Na2SO4) and concentrated. The residue was purified by preparative HPLC using a gradient elution from 15% to 50% acetonitrile in water to obtain 28 mg (26%) of the desired product. 1H NMR (300 MHz, DMSO-d6) δ 8.56 (s, 1 H), 7.97 (d, 2 H), 7.94 (s, 1 H), 7.81 (d, 1 H), 7.66-7.64 (m, 1 H), 7.36-7.26 (m, 5 H), 7.19 (dd, 1 H), 7.06-7.01 (m, 3 H), 5.66 (s, 2.
