Procedure
To methyl 3-(R)-n-butyl-3-[2-(S)-tert-butoxycarbonylpyrrolidin-1-ylcarbonyl)-2-(R)-benzoyloxypropionate H-2 (8.7 mmol) in methanol (25 mL) at 0° C. was added sodium methoxide (catalytic; pH adjusted to 10) and the solution stirred for 2 h. Amberlite IR-120 resin (H+ form) was added, then the solution was filtered and concentrated to afford methyl 3-(R)-n-butyl-3-[2-(S)-tert-butoxycarbonylpyrrolidin-1-yl-carbonyl)-2-(R)-hydroxypropionate H-3 (quant.).
