| Reactant | Ammonium Hydroxide | HCID 14923 | — |
| Reactant | (R/S)-2-(3-trimethylsilyloxy-2-oxo-1-pyrrolidinyl)acetamide | HCID 14028503 | — |
| Product | 1-Pyrrolidineacetamide, 3-hydroxy-2-oxo-, (+-)- | HCID 3069854 | — |
Reaction Steps
Ethyl of (R/S)-2-(3-trimethylsilyloxy-2-oxo-1-pyrrolidinyl)acetate is obtained analogously to the process in accordance with paragraph (a) of Example 1. After treatment with 25% ammonium hydroxide solution and acidic hydrolysis of the (R/S)-2-(3-trimethylsilyloxy-2-oxo-1-pyrrolidinyl)acetamide, there is obtained crude (R/S)-2-(3-hydroxy-2-oxo-1-pyrrolidinyl)acetamide. After chromatography on silica gel (granular size 0.2-0.5 mm) and elution with acetonitrile/methanol (1:1) (R/S)-2-(3-hydroxy-2-oxo-1-pyrrolidinyl)acetamide in about 80-90% purity can be detected.
