Procedure

To a sample of 114 (0.3004 g, 0.82 mmol) dissolved in 1,4-dioxane (15 mL) was added a solution of 2-(aminomethyl)-1-ethylpyrrolidine (0.12 mL, 0.82 mmol) in acetone (1 mL) followed by the addition of NaOH (0.33 mL, 2.5 N, 0.82 mmol) and water (1 mL). The reaction mixture was allowed to stir at reflux for about 2 hours under nitrogen. The reaction mixture was extracted 3 times with dichloromethane; the combined organic layers were washed with brine and dried over potassium carbonate. The sample was concentrated on the rotary evaporator and the resulting solid was dried overnight under vacuum. Column chromatography (silica gel, 93:6:1 dichloromethane: methanol: conc. ammonium hydroxide) yielded a light yellow solid, compound 116 (226 mg, 60%), mp 59° C.; HPLC: Inertsil ODS-3V C18, 40:30:30 [KH2PO4 (0.01M, pH 3.2): CH3OH: CH3CN], 264 nm, Rt 10.5 min, 100% purity; 1H NMR (600 MHz, CDCl3, 55° C.) δ 7.65 (broad resonance, rotamers, 1H), 7.07 (br d, J=7.8 Hz, 1H), 6.90 (t, J=9 Hz, 1H) 6.84 (broad resonance, rotamers, 1H), 4.12 (s, 2H), 3.88 (S, 3H), 1.02 (s, 1H), 2.26 (apt sextet, J=6.6 Hz, 1H), 2.19 (q, J=9 Hz, 1H), 1.16–1.92 (m, 10H), 1.57 (s, 2H), 1.17–1.32 (m, 3H), 1.05–1.11 (m, 4H); MS (ESI): m/z 459 (M+H, 100), 363 (40.7), 223 (16.1), 202 (4.4), 138 (1.2).
