Procedure
A solution of benzyl 2(S)-morpholinocarbonyloxy-3-phenylpropionate (300 mg) in methanol (20 ml) was hydrogenated over 10% palladium on carbon (30 mg) at 3 atmospheric pressure of hydrogen for 1 hour. The solution was filtered and concentrated in vacuo to give 2(S)-morpholinocarbonyloxy-3-phenylpropionic acid (220 mg) as an oil.
