Versuchsvorschrift

To a solution of tert-butyl 4-({[(2S,5R)-6-(benzyloxy)-7-oxo-1,6-diazabicyclo[3.2.1]oct-2-yl]carbonyl}amino)piperazine-1-carboxylate 206 (0.25 g, 0.54 mml) in methanol (15 mL) was added 10% Pd/C (0.3 g). The mixture was hydrogenated under 35 psi hydrogen atmosphere at room temperature for 2 h. The catalyst was filtered out through Celite, and the filtrate was evaporated to give tert-butyl 4-({[(2S,5R)-6-hydroxy-7-oxo-1,6-diazabicyclo[3.2.1]oct-2-yl]carbonyl}amino)piperazine-1-carboxylate 207 (0.20 g, 99%) as a colorless foam.

Aufarbeitung

  1. filtrationThe catalyst was filtered out through Celite
  2. customthe filtrate was evaporated
