Participants

Reaction Steps

The title compound was prepared as described for Example 67 using methyl 3-{5-[(diethylamino)methyl]pyridin-2-yl}-2-hydroxy-1H-indole-5-carboxylate (0.071 g, 0.2 mmol) and (2-aminoethyl)methylsulfone hydrochloride (0.080 g, 0.5 mmol) as starting materials. The base was obtained after preparative HPLC purification (XTerra®PrepMS C8 columns 10 μm, 19×300 mm; 0.1 M NH4OAc buffer/acetonitrile, from 90:10 to 40:60, as eluent gradient) as an orange yellow solid (0.030 g, 34% yield), which was transformed to the yellow hydrochloride salt (0.023 g, 72% yield): 1H NMR (CD3OD, 400 MHz) δ 8.21 (s, 1H), 8.11 (s, 1H), 7.95 (s, 2H), 7.60 (dd, J=8.0, 1.2 Hz, 1H), 7.14 (d, J=8.0 Hz, 1H), 4.35 (s, 2H), 3.93 (t, J=6.4 Hz, 2H), 3.51 (t, J=6.4 Hz, 2H), 3.29 (m, 4H), 3.09 (s, 3H), 1.43 (t, J=7.2 Hz, 6H); MS (EI) m/z 445 (M++1).
