実験手順

To a solution of 4-(4-amino-2-fluorophenoxy)-5-methylpyrrolo[2,1-f][1,2,4]triazin-6-yl ethylcarbamate (10 mg, 0.029 mmol) in CH2Cl2 (1 mL) was added a solution of 2-(4-fluorophenyl)acetyl isocyanate (2 mL, 0.25 M in dichloroethane). The reaction was stirred at room temperature for 1 h, LC/MS analysis indicated consumption of starting carbamate. The mixture was concentrated in vacuo and the residue was suspended in methanol and filtered to give the title compound. The filtrate was purified by flash chromatography to provide more of the title compound as a pale yellow solid (combined yield 5.9 mg, 40%). 1H NMR (CDCl3) 10.63 (s, 1H), 8.42 (s, 1H), 7.88 (s, 1H), 7.82 (s, 1H), 7.67 (dd, 1H, J=12.1, 2.2 Hz), 7.28 (m, 4H), 7.10 (m, 2H), 3.73 (s, 3H), 3.36 (m, 2H), 2.48 (s, 3H), 1.26 (m, 3H); MS(ESI+) m/z 525 (M+H)+.
