palladium; In ethanol; (b) Sarcosine, 1,1-dimethylethyl ester N-[(Phenylmethoxy)carbonyl]-sarcosine,1,1-dimethylethyl ester (68 g., 238 mmole) is taken into absolute ethanol (500 ml.) and stirred under hydrogen in the presence of 10% palladium on carbon catalyst (6.6 g.) overnight at room temperature. The reaction mixture is then filtered to remove the catalyst and concentrated in vacuo to remove the ethanol and give 20.6 g. of sarcosine,1,1-dimethylethyl ester as an oil.
