실험 절차

4-(methylamino)piperidine-4-carboxamide (250 mg, 1.59 mmol), potassium carbonate (264 mg, 1.91 mmol) and 2-bromopropane (0.179 ml, 1.91 mmol) in acetonitrile (10 ml) were heated at reflux for 1.5 hours. The mixture was cooled, filtered and concentrated under reduced pressure. The residues were purified by column chromatography on silica eluting with ammonia in methanol/dichloromethane (90/10) to give 1-isopropyl-4-(methylamino)piperidine-4-carboxamide (153 mg, 48%) as a white solid. 1H NMR Spectrum: (DMSO-d6) 0.92 (d, 6H); 1.45 (m, 2H); 1.77 (m, 2H); 1.86 (s, 1H); 2.06 (s, 3H); 2.38 (m, 4H); 2.59 (m, 1H); 6.82 (s, 1H); 7.15 (s, 1H).
