Stage #1: With sodium methylate In methanol at 20℃; for 4 h; Inert atmosphere; Reflux
Stage #2: With hydrogenchloride In ethanol
L-Lysine hydrochloride (100.0 g, 547 mmol) dissolved inMeOH (1200 mL) was stirred for 30 min at 0 C under Ar. Thionyl chloride (80 mL, 1.10 mol) was addeddropwise over 20 min at 0 C. The solution was stirred for 1 h at room temperature, and refluxed forovernight. After removal of the solvent in vacuo, the crude product was recrystallized from MeOH to givemethyl L-lysinate dihydrochloride (124.1 g, yield 97percent). Methyl L-lysinate dihydrochloride (60.0 g, 257mmol) dissolved in MeOH (1200 mL) was stirred at room temperature under Ar. NaOMe (48.0 g, 889mmol) was added, and the solution was refluxed for 4 h. The mixture was hydrolyzed by addingammonium chloride (20.0 g), and the solution was filtered, and then the solvent was removed in vacuo.The residue was dissolved in dimethoxyethane (80 mL), and the solution was filtered, and then thesolvent was removed in vacuo. The residue was dissolved in EtOH (100 mL), and EtOH saturated withHCl (20 mL) was added to give the crude product. The crude product was recrystallized from MeOH togive (S)-3-aminozepan-2-one hydrochloride (5: 27.8 g, yield 66percent)
