YieldReaction ConditionsOperation in experiment
99% With hydrogenchloride In tetrahydrofuran; 1,4-dioxane at 20℃; In tetrahydrofuran (6 ml) was dissolved tert-butyl 1-benzyl-5-oxo-3-pyrrolidinylcarbamate (480 mg, 1.65 mmol), followed by adding thereto 4N-hydrogen chloride/dioxane (6.0 ml, 24 mmol), and the resulting mixture was stirred overnight at room temperature. After completion of the reaction, diethyl ether (35 ml) was added to the reaction solution, and the resulting mixture was stirred at room temperature for 30 minutes and the precipitate was collected by filtration. The precipitate was washed with diethyl ether and dried to obtain 4-amino-1-benzyl-2-pyrrolidinone hydrochloride (380 mg, 99percent).1H-NMR (DMSO-d6) δ; 2.23 (1H, dd, J=4.0, 17.2Hz), 2.76 (1H, dd, J=8.6, 17.2Hz), 3.22 (1H, dd, J=4.0, 10.8Hz), 3.53 (1H, dd, J=7.7, 10.8Hz), 3.89 (1H, bs), 4.30 (1H, d, J=15.0Hz), 4.45 (1H, d, J=15.0Hz), 7.30 (5H, m), 8.32 (2H, bs).

YieldReaction ConditionsOperation in experiment
51% for 2 h; Heating / reflux In tert-butyl alcohol (6 ml) was dissolved 1-benzyl-5-oxo-3-pyrrolidinecarboxylic acid (1.00 g, 4.56 mmol), and triethylamine (0.76 ml, 5.5 mmol) was added thereto. Then, a solution of diphenylphosphoryl azide (1.38 g, 5.02 mmol) in tert-butyl alcohol (4 ml) was added thereto, and the resulting mixture was refluxed for 2 hours. After completion of the reaction, the reaction solution was concentrated and the tert-butyl alcohol was removed as an azeotrope with toluene as much as possible. The residue was purified by a silica gel chromatography (eluent: ethyl acetate/hexane) to obtain tert-butyl 1-benzyl-5-oxo-3-pyrrolidinylcarbamate (480 mg, 51percent).1H-NMR (DMSO-d6) δ; 1.34 (9H, s), 2.23 (1H, dd, J=5.7, 16.8Hz), 2.61 (1H, dd, J=8.6, 16.8Hz), 3.01 (1H, dd, J=5.7, 9.9Hz), 3.43 (1H, dd, J=8.6, 9.9Hz), 4.03 (1H, m), 4.36 (2H, s), 7.30 (6H, m).
