Reaction Steps

The 5-Bromo-3-(4-fluoro-benzenesulfonyl)-1-methyl-1H-indole (0.30 g, 0.85 mmol) was mixed with piperazine (0.34 g, 4 mmole) and methyl sulfoxide (3 mL). The mixture was heated at 120° C. in a sealed tube for 3 hours. The mixture was diluted with 10 mL water and the resultant precipitate was collected by filtration, washed with water, and recrystallized from chloroform/benzene to provide 5-Bromo-1-methyl-3-(4-piperazin-1yl-benzenesulfonyl)-1H-indole (0.302 g, 0.695 mmol), M+H 436.
