実験手順
A mixture of 0.2 g (0.79 mmole) 4-(4-methyl-piperazin-1-yl)-1H-indole dihydrochloride, 0.2 g (1.03 mmole) 4-fluorobenzenesulfonyl chloride and 0.025 g tetrabutylammonium hydrogen sulfate in 5 mL 4M sodium hydroxide and 15 mL toluene was stirred at room temperature for 24 hrs. The mixture was diluted with 10 mL water and extracted with 25 mL ethyl acetate. The organic phase was washed with 5 mL water, 5 mL saturated sodium chloride, dried (magnesium sulfate) and concentrated under reduced pressure. The hydrochloride salt was recrystallized from ethyl acetate/ether to provide 0.208 g of 1-(4-fluoro-benzenesulfonyl)-4-(4-methyl-piperazin-1-yl)-1H-indole (32), m.p. 151-152° C.
