実験手順
A solution of 2-(6-chloro-3-vinylpyridazin-4-yl)-4-fluoro-1H-indole (80 mg, 0.29 mmol) in HCl-dioxane (5 mL) was stirred at 50° C. After 15 minutes, NaHCO3 (a.q) was added. The mixture was extracted with DCM. The organic phase was dried over Na2SO4. After being concentrated in vacuo, the residue was purified by prep-TLC (DCM) to give the product of 2-(6-chloro-3-(2-chloroethyl)pyridazin-4-yl)-4-fluoro-1H-indole (60 mg, yield: 66%). 1H-NMR (CDCl3, 400 MHz) δ 9.04 (s, 1H), 7.63 (s, 1H), 7.28˜7.31 (m, 1H), 7.22˜7.26 (m, 1H), 6.99 (d, J=1.6 Hz, 1H), 6.84˜6.93 (m, 1H), 4.24 (t, J=6.4 Hz, 2H), 3.66 (t, J=6.5 Hz, 2H). MS (M+H)+: 310/312.
