Reaction Steps

To a solution of (2R)-1-tert-butoxycarbonylpyrrolidine-2-carboxylic acid (810 mg, 3.8 mmol) and HATU (1.40 g, 3.8 mmol) in DMF (7.5 mL) was added ethanamine (3.8 mL of 2 M, 7.5 mmol) followed by DIEA (1.0 g, 1.4 mL, 8.0 mmol) at room temperature. The reaction mixture was stirred at room temperature for 16 h. The reaction mixture was diluted with EtOAc and washed sequentially with 1M HCl, saturated NaHCO3 and brine solution. The organic layer was dried (Na2SO4) filtered and concentrated under reduced pressure to obtain tert-butyl (2R)-2-(ethylcarbamoyl)pyrrolidine-1-carboxylate (624 mg, 68%). LC/MS m/z 243.4 [M+H]+.
