YieldReaction ConditionsOperation in experiment
56% With triethylamine; In dichloromethane; at 20℃; (2S)-4-Bromo-2-tert-butoxycarbonylamino-butyric acid methyl esterMe O2C ^// BrNHBoc[0545] Et3N (6.5 mL, 47 mmol) followed by BoC2O (4.09 g, 18.8 mmol) were added to a solution of 2-amino-4-bromo-butyric acid methyl ester hydrobromide (5.2 g, 19 mmol) in CH2Cl2 (100 mL) at rt. The reaction mixture was stirred O/N at rt and then quenched with H2O (100 mL). The aqueous layer was extracted with CH2Cl2, dried (MgSO4), and concentrated in vacuo. The residue was purified by flash chromatography (20% EtOAc in hexane) to give the title compound as a colorless liquid: yield 3.1 g (56%).[0546] 1H NMR (400 MHz, CDCl3) δ (ppm): 5.19-5.00 (m, IH), 4.51-4.37 (m, IH), 3.77 (s, 3H), 3.44 (t, J= 7.0 Hz, 2H), 2.47-2.32 (m, IH), 2.27-2.13 (m, IH), 1.45 (s, 9H).
