実験手順

A solution of 3-benzenesulfonyl-7-piperazin-1-yl-1H-indole (101) (500 mg, 1.46 mmol) and 1 mL of 37% aqueous formaldehyde in 25 mL of ethanol was hydrogenated at atmospheric pressure in the presence of 250 mg of 10% Pd-C for 30 min. The mixture was filtered, diluted with water and extracted with ethyl acetate. The ethyl acetate was washed with water and brine, dried, and evaporated to yield the crude free base of 3-benzenesulfonyl-7-(4-methyl-piperazin-1-yl)-1H-indole. The hydrochloride salt was crystallized from ethanol-ether to afford 290 mg of (501), m.p. 160-162° C.
