Procedure

An ethanolic solution of 1-[2-(benzyloxycarbonylamino)propanoyl]-2,2-dimethyl-4-imidazolidinone (4.9 g) containing 1 g of 5% palladium on charcoal was stirred at room temperature while hydrogen was bubbled into the solution for 1 hour. Removal of the catalyst, evaporation of the solvent, and trituration of the residue with ethyl acetate afforded the title compound as a white powder m.p. 156° C. (decomp).
