A mixture of (R)-3-(N-benzyloxycarbonylpyrrolidin-2-ylmethyl)-5-dibenzylamino-1H-indole (7.90 g, 14.91 mmol) and moist palladium (ll) hydroxide on carbon (Peariman's catalyst, 3.16 g) in absolute ethanol (100 mL) was shaken under a hydrogen atmosphere (3 arm) for 12 hours at room temperature. The resulting mixture was filtered through diatomaceous earth, and the filtrate was evaporated and dried under reduced pressure to afford the title compound as a white foam (3.20 g, 100%): 1H NMR (CD3OD) δ7.18 (d, J=8.5 Hz, 1H), 7.08 (s, 1H), 6.92 (d, J=2.0 Hz, 1H), 6.69 (dd, J=1.9 and 8.5 Hz, 1H),3.81-3.69(m, 1H),3.30-2.95(m,4H), 2.09-1.55(m, 4H); 13C NMR (CD3OD) δ140.1, 133.4, 129.1, 125.0, 114.6, 113.1, 109.8, 105.1, 62.1, 46.0, 31.1, 29.1, 24.3; LRMS (m/z, relative intensity) 215 (M+, 2), 198 (1), 146 (100), 128 (7), 117 (9), 70 (60).
