Propargyl alcohol → (5R)-3-(3-Fluoro-4-iodophenyl)-5-[(4-hydroxymethyl-1H-1,2,3-triazol-1-yl)methyl]oxazolidin-2-one

Participants

Reaction Steps

(5R)-5-(Azidomethyl)-3-(3-fluoro-4-iodophenyl)-1,3-oxazolidin-2-one (Intermediate 5, 10 g, 28 mmol) was dissolved in acetonitrile (80 mL). Propargyl alcohol (3.2 mL, 56 mmol) was added and then CuI (526 mg, 2.8 mmol) and it was stirred overnight. The solidified reaction mixture was extracted with ethyl acetate/acetonitrile, washed with water and dried over magnesium sulfate. Evaporation of solvent under vacuum gave 12.3 g crude product (quantitative).
