実験手順

To a solution of the compound (0.91 g, 1.8 mmol) obtained in step 1 in ethanol (40 ml) was added a catalytic amount of 10% palladium/carbon, and the mixture was stirred for 3 hours under a hydrogen atmosphere. The catalyst was filtered off, and the filtrate was concentrated under reduced pressure to give the title compound (0.66 g, 1.8 mmol, 99%).

後処理

  1. filtrationThe catalyst was filtered off
  2. concentrationthe filtrate was concentrated under reduced pressure
