実験手順

To a solution of methyl 2-(4-(4-amino-1-((2-(trimethylsilyl)ethoxy)methyl)-1H-indazol-5-yloxy)-3-methoxyphenyl)acetate (42 mg, 0.092 mmol) in dichloromethane (1 mL) was added 2,4-dichlorobenzene sulfonyl chloride (25 mg, 0.1 mmol) and pyridine (10 μl, 0.12 mmol). The resulting mixture was stirred overnight at room temperature. The mixture was then diluted with dichloromethane (20 mL) and washed with dilute aqueous hydrochloric acid (20 mL) and water (20 mL), then dried over magnesium sulfate and concentrated under reduced pressure. The desired sulfonamide was isolated by column chromatography (10% ethyl acetate/hexane). 1H NMR (400 MHz) (CDCl3) δ 8.40 (s, 1H); 7.81 (s, 1H); 7.72 (d, J=8.5 Hz, 1H); 7.32 (d, J=9 Hz, 1H); 7.19 (d, J=1.9 Hz, 1H); 7.15 (dd, J=1.9, 8.5 Hz, 1H); 6.90 (d, J=1.8 Hz, 1H); 6.88 (d, J=9 Hz, 1H); 6.60 (dd, J=1.8, 8.2 Hz, 1H); 6.35 (d, J=8.2 Hz, 1H); 5.68 (s, 2H); 3.84 (s, 3H); 3.75 (s, 3H), 3.62 (s, 2H); 3.57 (t, J=8.2 Hz, 2H); 0.89 (t, J=8.2 Hz, 2H), 0.0 (s, 9H).
