N-benzothiazol-2-yl-4-piperazin-1-yl-benzamide trifluoroacetate (40 mg) was mixed with 2-oxa-spiro[4,4]nonane-1,3-dione (30 mg) in DMF (5 mL) containing triethylamine (0.1 mL) and the mixture was stirred foe 5 hrs. Solvents were evaporated and the residue was treated with ethyl acetate and hydrochloric acid solution (0.1N).
