実験手順

(S)-2,5-Dioxopyrrolidin-1-yl 2-(tert-butoxycarbonylamino)propanoate (130 mg, 0.45 mmol) was added to amine 5 (110 mg, 0.35 mmol) and Et3N (94.4 mg, 130 μL, 0.93 mmol) in DCM (2 mL) and DMF (0.2 mL) and the mixture was stirred at room temperature for 36 h. DCM was added followed by 1N HCl and the organic layer was separated and washed with H2O, then with saturated NaHCO3, dried over MgSO4, filtered and concentrated. The crude material was purified by chromatography (Biotage, 25+S column) eluting with 0-50% EtOAc/hexanes. Compound 6 was obtained in 49% yield as a white solid. LRMS (ESI): calc. 484.5; found 507.1 (MNa)+.
