Procedure

In 140 ml of methanol was dissolved 4.41 g of compound (30) and the compound was hydrogenated using 426 mg of 10% palladium-carbon as a catalyst. The catalyst was filtered off and the filtrate was concentrated to provide 2.41 g of (S)-N-butyl-2-pyrrolidinecarboxamide (31).

Workup

  1. filtrationThe catalyst was filtered off
  2. concentrationthe filtrate was concentrated
