2.05 g (9 mmol) 1-(4-Fluoro-phenyl)-1H-indol-5-ol in 25 ml acetone were treated with 4.7 ml (30 mmol) 1,6-dibromohexane and 4.14 g (30 mmol) K2CO3 powder in 25 ml acetone. The mixture was stirred at 55° C. for 6 h, and at RT for 20 h. Acetone was added, and the suspension filtered. Purification of the crude product with column chromatography with hexane/EtOAc 49:1 yielded 2.4 g (68%) 5-(6-Bromo-hexyloxy)-1-(4-fluoro-phenyl)-1H-indole as colorless solid, MS: 389 (M, 1Br, 1Cl).
