Versuchsvorschrift

3.7 ml of concentrated hydrochloric acid was added to a methanol solution of 9.5 g of 1-benzo[b]thiophen-4-yl-piperazine, and the solvent was evaporated under reduced pressure. Ethyl acetate was added to the residue and precipitated crystals were filtrated and recrystallized from methanol and 1-benzo[b]thiophen-4-yl-piperazine hydrochloride was obtained as colorless needle-like crystals.
