الإجراء التجريبي
To 101 (6.03 g, 20.0 mmol) dissolved in acetone (75 mL) was added a solution of 1-aminohomopiperidine (2.3 mL, 20.0 mmol) in acetone (10 mL) followed by addition of NaOH (8.0 mL 2.5 N NaOH solution, 20.0 mmol) and 20 mL of water. The reaction mixture was allowed to stir at reflux overnight 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 a rotary evaporator and the resulting oil was dried overnight under vacuum. Column chromatography (96:3:1 dichloromethane: methanol: conc. ammonium hydroxide) yielded a light purple solid 152 (1.2 g, 16%), mp 139° C.; TLC (silica gel, 96:3:1, CH2Cl2, CH3OH, conc. NH4OH), Rf 0.31; HPLC: Inertsil ODS-3V C18, 40:30:30 [KH2PO4 (0.01M, pH 3.2): CH3OH: CH3CN], 264 nm, Rt 52.5 min, 94.9% purity; MS (ESI): m/z 383 (M+H, 100).
