YieldReaction ConditionsOperation in experiment
With sodium methylate;palladium-carbon catalyst; In methanol; EXAMPLE 3 Production of (S)-4-hydroxy-2-pyrrolidinone Ethyl (S)-4-azido-3-hydroxybutyrate (4.8 g, 27.7 mmol) was dissolved in methanol (50 ml) and 5% palladium-carbon catalyst (100 mg) and a 28% methanol solution of sodium methoxide (280 mg, 1.4 mmol as NaOMe) were added thereto. The mixture was stirred at room temperature for 2.5 hours with blowing hydrogen gas to effect reduction and subsequent ring-closing reactions. The catalyst was filtered off and the filtrate was concentrated under reduced pressure. The resulting crude crystals were recrystallized from ethanol (17 ml) to obtain colorless crystals. The yield was 2.1 g (76%) and the melting point was 156.7-157.6 C. The NMR data, IR data, and behavior during the HPLC analysis using an optical resolution column of the thus-obtained colorless crystals were identical with those obtained in Example 1.
