실험 절차

Concentrated HCl (10 mL) was added to a suspension of a 2:1 mixture of 2-(6-bromo-1H-indol-3-yl)ethanamine and 2-(4-bromo-1H-indol-3-yl)ethanamine (9.90 g, 41.4 mmol) and Na2SO4 (30 g) in 1:1 acetone/n-butanol (100 mL). The resulting suspension was heated at 60° C. with stirring for 4 d. The suspension was cooled and concentrated under reduced pressure. The residue was diluted with EtOAc, and the suspension was filtered. The filtrate was washed with saturate NaHCO3 solution, dried over Na2SO4 and concentrated under reduced pressure. Flash chromatography (silica gel, (1:1 EtOAc/hexanes)/(9:0.9:0.1 CH2Cl2/MeOH/NH4OH) 100:0 to 0:100) yielded the title compound (1.68 g, 15%) as a red foam: 1H NMR (500 MHz, CDCl3) δ 7.66 (br s, 1H), 7.45 (d, J=1.5 Hz, 1H), 7.32 (d, J=8.5 Hz, 1H), 7.19 (dd, J=8.5, 1.5 Hz, 1H), 3.20 (t, J=5.5 Hz, 2H), 2.68 (t, J=5.5 Hz, 2H), 1.47 (s, 6H).
