実験手順
4-(3-Benzenesulfonyl-1H-indol-7-yl)-piperazine-1-carboxylic acid tert-butyl ester (1 g, 2.2 mmol) was dissolved in 5 mL of dichloromethane and 6 mL of trifluoroacetic acid was added. After 10 min the mixture was concentrated in vacuo, taken into water, and washed with ether. The aqueous layer was basified with ammonium hydroxide, extracted with dichloromethane, and the extract was dried (sodium sulfate) and evaporated to afford the crude free base. The hydrochloride salt was crystallized from ethanol to afford 550 mg of 3-benzenesulfonyl-7-piperazin-1-yl-1H-indole hydrochloride (101), m.p. 278-280° C.
