実験手順

Iodomethane (0.568 ml, 9.12 mmol) was added to a solution of 1-(3,5-difluoro-benzyl)-3-(2-nitro-phenylsulfanyl)-1H-indol-6-ylamine (Example 15a; 2.5 g, 6.1 mmol) in a mixture of ethanol and tetrahydrofuran containing sodium carbonate (0.657 g, 6.08 mmol). The reaction mixture was heated under reflux overnight and concentrated. Water was added and the product was extracted into ethyl acetate. The combined organic phases were washed with water and brine, dried over sodium sulfate and concentrated under reduced pressure. Column chromatography (heptane/ethyl acetate 8:2) afforded [1-(3,5-difluoro-benzyl)-3-(2-nitro-phenylsulfanyl)-1H-indol-6-yl]-methyl-amine (0.647 g) and [1-(3,5-difluoro-benzyl-3-(2-nitro-phenylsulfanyl)-1H-indol-6-yl]-dimethyl-amine (0.815 g). 1H-NMR (CDCl3) δ 8.26 (dd, 1H, J=8.2 and 1.2 Hz), 7.35 (d, 1H, J=8.6 Hz), 7.27 (ddd, 1H, J=8.2, 7.4 and 1.2 Hz), 7.25 (s, 1H), 7.17 (ddd, 1H, J=8.2, 7.4 and 1.2 Hz), 7.03 (dd, 1H, J=8.2 and 1.2 Hz), 6.78 (dd, 1H, J=8.6 and 2.3 Hz), 6.74 (tt, 1H, J=8.6 and 2.3 Hz), 6.68 (m, 2H), 6.48 (d, 1H, J=2.3 Hz), 5.29 (s, 2H), 2.95 (s, 6H).
