Versuchsvorschrift
1-{5-[4-(4-Trifluoromethyl-phenyl)-piperazine-1-sulfonyl]-2,3-dihydro-indol-1-yl}-ethanone was refluxed in 1,4-dioxane (5 mL) and concentrate HCl (2.5 mL) for 2 h. The reaction was then diluted with dichloromethane and washed with 1N HCl, saturated sodium bicarbonate, dried (Na2SO4), filtered and concentrated to provide 5-[4-(4-trifluoromethyl-phenyl)-piperazine-1-sulfonyl]-2,3-dihydro-1H-indole (1.03 g, 75%) as an off-white solid. 1H NMR (400 MHz, CDCl3) δ 7.48-7.20 (m, 4H). 6.88 (d, 2H), 6.60 (d, 1H), 3.70 (t, 2H), 3.36-3.33 (m, 4H), 3.15-3.12 (m, 4H), 3.10 (t, 2H).
