Versuchsvorschrift
A mixture of 6-chloro-2-(1H-indol-2-yl)pyridin-3-ol (244 mg, 1 mmol, described in Example 1) and NCS (160 mg, 1.2 mmol) in Acetone (2 mL) was stirred at room temperature for 1 hour. The mixture was then concentrated and purified using prep-TLC (petroleum ether:EtOAc=2:1) to provide 6-chloro-2-(3-chloro-1H-indol-2-yl)pyridin-3-ol (180 mg, yield: 64.7%). 1H-NMR (CDCl3, 400 MHz) δ 9.03 (s, 1H), 7.61 (d, J=7.6 Hz, 1H), 7.15˜7.36 (m, 5H), 6.20˜6.40 (br s, 1H). MS (M+H)+: 279/281.
