100% | To a solution of 5-fluoroindole -3-acetic acid (ig, 5.2mmol) in THE (2Oml) was added a1M solution of lithium aluminium hydride in THE (10.4m1, 10.4mmol) and the mixturerefluxed for 1.5 hours. The mixture was cooled, 0.39m1 of water and then 0.39m1 of15% NaOH(aq) added, followed by I .2m1 of water. The precipitate was collected viavacuum filtration and the filtrate concentrated to give 2-(5-fluoro-1 H-indol-3-yl)ethanol,an orange oil (0.927g, 100%); ?H NMR (400 MHz, CHLOROEORM-d) 6 ppm 2.98 (t,J=6.41 Hz, 2 H)1 3.89 (t, J=6.18 Hz, 2 H), 6.95 (td, J9.04, 2.52 Hz, I H), 7.12 (s, 1 H), 7.22 - 7.30 (m, 2 H), 8.06 (br.

70% | With carbon tetrabromide; triphenylphosphine; In dichloromethane; at 0 - 20℃; for 5h; | To a solution of <strong>[101349-12-6]2-(5-fluoro-1H-indol-3-yl)ethanol</strong> (18a) (10g,55.8 mmol) in CH2Cl2 (200 mL) was added successively CBr4 (27.76 g, 83.71 mmol) and PPh3 (21.52 g, 82.03 mmol) at 0 C. Themixture was stirred at room temperature for 5 h. After thecompletion of reaction, the solvent was concentrated underreduced pressure. The residue was purified by column chromatographyon silica gel (PE/EA = 5:1, V/V) to give compound 19a as ayellow oil (9.46 g, 70%) [27]. MS (ESI) m/z: 242.06 [M+H]+. |
