실험 절차
A solution of 3-(5-fluoro-1H-indol-3-yl)-propan-1-ol (Intermediate 6) prepared in accordance with the procedures set forth in Demerson et al., J. Med. Chem., 19:391-395 (1976). (25.4 g, 0.13 mol), carbon tetrabromide (65.5 g, 0.2 mol) and triphenylphosphine (52 g, 0.2 mol) in methylene chloride (156 ml) was allowed to stir for 2 hours. The solvent was evaporated and the product chromatographed (30% ethyl acetate-hexanes) to afford 33.5 g (99%) of product.
