実験手順

The stirred solution of 25 g of 6-bromo-1H-indole [52415-29-9] in 250 ml of DMPU is admixed at 0° C. with 11.2 g of sodium hydride (60% in mineral oil) in portions. The mixture is stirred over 1 hour and then admixed with 60.9 g of 1-chloro-3-methoxypropane and 4.71 g of tetrabutylammonium iodide (exothermic reaction). The mixture is stirred at room temperature over a further 1 hour. The resulting reaction mixture is poured onto 2 l of water (cold) and extracted with tert-butyl methyl ether (2×). The combined organic phases are washed successively with water (3×) and brine, dried over sodium sulphate and filtered, and the filtrate is concentrated by evaporation. The title compound is obtained as a slightly yellowish oil from the residue by means of flash chromatography (SiO2 60 F). Rf=0.31 (1:2 EtOAc-heptane). Rt=5.10 (gradient I).
