Versuchsvorschrift

In 86 ml of ethanol was dissolved 4.3 g of compound (88) and after adding thereto 210 mg of 10% palladium-carbon, the mixture was stirred vigorously for 90 minutes in a hydrogen stream, After filtering off the catalyst, ethanol was distilled off under reduced pressure to provide 2.19 g of crude (S)-N,N-dimethyl-2-pyrrolidinecarboxamide (89).
