Versuchsvorschrift

A mixture of (1R)-N-benzyloxycarbonyl-4-hydroxy-1-(4,5-diphenyloxazol-2-yl)butylamine (12 g) and 10% Pd/C (2 g) in methanol (20 ml) was stirred under H2 for 5 hours. The catalyst was filtered off and filtrate was evaporated. The residue was recrystallized with ether to give (1R)-4-hydroxy-1-(4,5-diphenyloxazol-2-yl)butylamine (5.8 g).

Aufarbeitung

  1. filtrationThe catalyst was filtered off
  2. customfiltrate was evaporated
