Participants

Reaction Steps

A solution of triphosgene (0.431 g, 1.45 mmol) in THF (5 mL) was added dropwise to a stirred solution of (S)-2-aminopentan-1-ol (0.500 g, 4.85 mmol) and Et3N (1.49 mL, 10.7 mmol) in THF (22 mL) at 0° C. under N2. The reaction mixture was stirred at ambient temperature for 2 hours. After cooling, the suspension was filtered through GF/F paper and concentrated in vacuo. The residue was taken up in EtOAc and washed with 10% HCl, dried and concentrated to give (S)-4-propyloxazolidin-2-one (0.348 g, 55%) as a clear oil.
