실험 절차

To a mixture of 1-(3-fluoro-4-hydroxyphenyl)-3-(2-(4-fluorophenyl)acetyl)thiourea (60 mg, 0.19 mmol, Compound A of Example 3), 4-chloro-5-methylpyrrolo[2,1-f][1,2,4]triazin-6-yl pivalate (50 mg, 0.19 mmol, Compound D of Example 1) and 1,4-diazabicyclo[2.2.2]octane (DABCO, 21.3 mg, 0.19 mmol) was added MeCN (5 mL). The reaction was stirred at RT for 1 h and concentrated in vacuo. The residue was purified by flash chromatography (eluted with 1-15% MeOH/CH2Cl2) to give the title compound (91 mg, 86%) as a white solid. 1H NMR (CDCl3) δ 12.40 (s, 1H), 8.54 (s, 1H), 7.87 (m, 3H), 7.29 (m, 4H), 7.12 (m, 2H), 3.71 (s, 2H), 2.43 (s, 3H), 1.39 (s, 9H); MS(ESI+) m/z 554 (M+H)+.
