実験手順

A mixture of 2.18 g of 3-(4-aminobutyl)-5-ethoxycarbonylindole [obtainable from 5-ethoxycarbonylindole by reaction with 4-chlorobutyryl chloride, reduction of the product to give 3-(4-chlorobutyl)-5-ethoxycarbonylindole and conversion into 3(4-phthalimidobutyl)-5-ethoxycarbonylindole] and one equivalent of 6-N,N-bis(2-chloroethyl)amino)-1,4-benzodioxane ("B") in 40 ml of acetone and 40 ml of water is boiled for 24 hours and worked up in the conventional manner. 6-[4-(4-(5-ethoxycarbonylindol-3-yl)butyl)piperazino]-1,4-benzodioxane is obtained.
