Procedure

A solution of benzyl 2(S)-[N-(2-morpholinocarbonylethyl)-N-methylaminocarbonyloxy]-3-phenylpropionate (726 mg) in methanol (150 ml) and water (10 ml) was hydrogenated over 10% palladium on carbon (80 mg) at atmospheric pressure of hydrogen for 1 hour. The solution was filtered and concentrated in vacuo to give 2(S)-[N-(2-morpholinocarbonylethyl)-N-methylaminocarbonyloxy]-3-phenylpropionic acid (573 mg).
