Reaction Steps

Ethyl 3-[(2S,4R)-4-tert-butyldimethylsiloxy-N-tert-butoxycarbonylpyrrolidin-2-yl]acrylate (10 g, 26.8 mmol) was subjected to catalytic hydrogenation in ethanol (200 ml) by means of 10% palladium carbon (500 mg) at 60° C. for 3 hours. The reaction solution was left to cool, and the catalyst was filtered off. The filtrate was concentrated under reduced pressure, and the residue was subjected to silica gel column chromatography (Wakogel™ C-300, 300 ml, ethyl acetate-hexane 1:10) to obtain ethyl 3-[(2R,4R)-4-tert-butyldimethylsiloxy-N-tert-butoxycarbonylpyrrolidin-2-yl]propionate (9.91 g, yield: 98%).
