Participants

Reaction Steps

(2S,4R)-1-p-Nitrobenzyloxycarbonyl-2-formylmethyl-4-t-butyldimethylsilyloxypyrrolidine (423 mg) was dissolved in 2 ml of ethanol, and 65 mg of N,N-dimethylhydrazine was added thereto, followed by stirring at room temperature for 15 minutes. To the reaction mixture was added ethyl acetate, and the mixture was washed with water, dried over anhydrous sodium sulfate and distilled to remove the solvent. The residue was purified by silica gel thin layer chromatography to obtain (2R,4R)-1-p-nitrobenzyloxycarbonyl-2-(2-dimethylhydrazinoethyl)-4-t-butyldimethylsilyloxypyrrolidine.
