Versuchsvorschrift
9.12 g (0.04 mole) of N-(2-oxo-1-pyrrolidineacetyl)-glycine ethyl ester are heated for 12 hours under reflux with 7.7 g (0.1 mole) of n-butylamine. The reaction mixture is evaporated to dryness and the crystallized residue is washed with diethyl ether. The residual product is dried after filtration and washing with diethyl ether. 9.9 g of N-n-butyl-2-(2-oxo-1-pyrrolidineacetamido)-acetamide are thus obtained (yield: 97% of theory); M.P. 105°-106° C.
