実験手順
In analogy to example 3.1, 2,3-Dimethyl-1H-indol-5-ol [for preparation see for example: Roth, H. J.; Lepke, P. Synthesis of indole and carbazole derivatives by condensation of α-hydroxyketones and aromatic amines. Arch. Pharm. (Weinheim) (1972), 305(3), 159-71.] and 1,4-dibromobutane were converted to yield 5-(4-Bromo-butoxy)-2,3-dimethyl-1H-indole as white solid, mp 119-120° C., MS: 295 (M, 1Br).
