Versuchsvorschrift

8.6 g of 1-[4-(5-cyanoindol-3-yl)butyl]4-(2-carbamoyl-benzofuran-5-yl)-piperazine is dissolved in tetrahydrofuran and 19.4 ml 1N hydrochloric acid and 7.4 ml water are added within 30 minutes to this solution at 35-37° C. After stirring of five hours, precipitation occurs and suction filtration is effected. Drying in vacuo at room temperature to constant weight leads to the solvate of 1-[4-(5-cyanoindol-3-yl)butyl]4-(2-carbamoyl-benzofuran-5-yl)-piperazine hydrochloride with tetrahydrofuran of Form X which present the x-ray diffraction spectrum of FIG. 15.
