Participants

Reaction Steps

To a solution of (2S,4R)-2-acetoxymethyl-4-hydroxypyrrolidine (22.66 g) in water (100 ml), a solution of S-p-nitrobenzyloxycarbonyl-4,6-dimethyl-2-mercaptopyrimidine (34.45 g) in tetrahydrofuran (453 ml) was added at room temperature, followed by addition of triethylamine (22.54 ml). The resulting mixture was stirred at the same temperature for 30 minutes and diluted with ethyl acetate. The reaction mixture was washed successively with dilute hydrochloric acid and aqueous sodium chloride solution and dried over magnesium sulfate, followed by removal of the solvent. The residue was purified by silica gel column chromatography to give (2S,4R)-1-p-nitrobenzyloxycarbonyl-2-acetoxymethyl4-hydroxypyrrolidine.
