Procedure
17.1 g (0.075 mole) of N-(2-oxo-1-pyrrolidineacetyl)-glycine ethyl ester are dissolved in 350 ml of methanol. The solution is saturated with a current of ammonia (about 2 hours), stirring is maintained for 3 hours at ambient temperature. After the reaction mixture has been evaporated to dryness in vacuo, the residue crystallizes quickly, 14.9 g of 2-(2-oxo-1pyrrolidineacetamido)-acetamide being obtained (yield: 100% of theory); M.P. 147°-148° C.
