反応手順
To a solution of (R)-3-tert-butoxycarbonylamino-butyric acid (150 mg, 0.74 mmol) and HATU (309 mg, 0.81 mmol) in DMF (2 mL) was added pyrrolidine (0.19 mL, 2.21 mmol). The resultant yellow reaction mixture was stirred at room temperature overnight then quenched with water and extracted with EtOAc (2×). The combined organics were washed with water (3×) and brine then dried over MgSO4 and concentrated to afford ((R)-1-methyl-3-oxo-3-pyrrolidin-1-yl-propyl)-carbamic acid tert-butyl ester as a colorless oil which was used without further purification.
