Versuchsvorschrift

To the solution of (3-methanesulfonyl-phenyl)-hydrazine (1.35 g) and 1-(4-fluoro-phenoxy)-propan-2-one (1.01 g) in benzene at RT was added equimolar amount of PCl3. The reaction mixture was stirred at RT for 1 hour and the solvent was removed in vacuo. The residue was purified by Biotage chromatography, eluted with 10–30% EtOAc/Hexane to yield 0.1 g of 3-(4-fluoro-phenoxy)-6-methanesulfonyl-2-methyl-1H-indole 401 as a light orange powder, MS: 320 ([M+H]+).
