1,1'-Carbonyldiimidazole → (4S,5R)-5-(4H-benzo[d][1,3]dioxin-7-yl)-4-methyloxazolidin-2-one

Participants

Reaction Steps

A mixture of (1R,2S)-2-amino-1-(4H-benzo[d][1,3]dioxin-7-yl)propan-1-ol hydrochloride (I3b) (120 mg, 0.49 mmol), DIEA (0.100 mL, 0.59 mmol) and CDI (90 mg, 0.56 mmol) in THF (2 mL) was stirred at room temperature for 2 hours. The reaction mixture was concentrated by evaporation, the residual material was partitioned between EtOAc and water, the organic phase was washed with 10% NaHSO4, dried over MgSO4, filtered and evaporated. The crude product was analysed by LC/MS and was considered pure enough for further analysis by NMR. Yield 66 mg (57%)
