Reaction Steps

1.8 g of 3-(4-chlorobutyl)-5-methoxyindole [obtainable by diazotization of p-methoxyaniline, reaction with ethyl cyclohexanone-2-carboxylate according to Japp-Klingemann to give 4-(2-carbethoxyindol-3-yl)butyric acid, alkaline hydrolysis, decarboxylation, reduction with LiAlH4 and reaction with SOCl2 ] and 1.9 g of 1-(2-hydroxymethylbenzofuran-5-yl)piperazine [obtainable by reaction of N,N-bis(2-chloroethyl)amine with 2-hydroxymethyl-5-aminobenzofuran] are dissolved in 200 ml of acetonitrile and the mixture is stirred at room temperature for 10 hours. Customary working up gives 1-[4-(5-methoxyindol-3-yl)butyl]-4-(2-hydroxymethylbenzofuran-5-yl)piperazine, m.p. 159°.
