Procedure

10 g of 1-[4-(5-cyanoindol-3-yl)butyl]-4-(2-carbamoyl-benzofuran-5-yl)-piperazine dihydrochloride Form XIII are dispersed in 1 l water. After stirring for 48 hours the crystals are recovered by filtration, and drying in vacuo to constant weight at room temperature leads to 1-[4-(5-cyanoindol-3-yl)butyl]-4-(2-carbamoyl-benzofuran-5-yl)-piperazine hydrochloride hydrate of Form V.
