Versuchsvorschrift

A mixture of 1-[6-(1-benzyl-piperidin-4-ylamino)-2,3-dihydro-indol-1-yl]-ethanone (0.10 g, 0.29 mmol), 2-phenyl-ethenesulfonyl chloride (87 mg, 0.43 mmol), and TEA (0.08 mL, 0.57 mmol) in CH2Cl2 (5 mL) was stirred at rt for 20 h. The reaction mixture was concentrated, and the residue was purified on silica gel (60-70% EtOAc/hexanes) to afford the title compound (138 mg, 92%). 1H NMR (500 MHz, CDCl3): 8.12 (s, 1H), 7.50-7.48 (m, 2H), 7.43 (s, 1H), 7.41-7.39 (m, 3H), 7.25 (d, J=6.8 Hz, 2H), 7.20 (t, J=7.0 Hz, 3H), 7.15 (d, J=7.9 Hz, 1H), 6.91 (d, J=7.8 Hz, 1H), 6.86 (d, J=15.0 Hz, 1H), 4.13 (t, J=8.0 Hz, 2H), 3.98-3.40 (m, 1H), 3.41 (s, 2H), 3.20 (t, J=8.5 Hz, 2H), 2.87 (d, J=10.5 Hz, 2H), 2.20 (s, 3H), 2.06-2.02 (m, 2H), 1.88 (d, J=10.7 Hz, 2H), 1.61-1.55 (m, 2H). MS: exact mass calculated for C30H33N3O3S, 515.22; m/z found, 516.3 [M+H]+.
