反応手順
A solution of 7.1 g ethyl 4-hydroxy-2-oxo-1-pyrrolidineacetate obtained in Example 12, in 7.1 ml ammonia solution (d25 =0.90) is stirred at ambient temperature for 15 h. It is then diluted with 140 ml acetone and the mixture is stirred at ambient temperature until the gum that precipitates solidifies into white crystals. On filtering in vacuo and drying, 4-hydroxy-2-oxo-1-pyrrolidineacetamide is obtained, m.p. 160°-162° C.
