PROCEDURE
实验过程
To the crude methyl-(R)-4-(1-carbamoylpropylamino)butyrate (VIf) in toluene (20 ml) is added 2-hydroxypyrridine (50 mg, 10 mol %). The mixture is heated to 80° C. until complete conversion. After 16 hours (GC: 100% conversion) the mixture is concentrated to dryness to yield (R)-2-(2-oxopyrrolidin-1-yl)butyramide (0.28 g, 1.6 mmol, 30%, yield determination by GC assay from pure standard).
