Conditions

Detailed conditions
See reaction.notes.procedure_details.

Workup

  1. 1
    Filtrationthe mixture was filtered through celite (prewashed with MeOH and EtOAc, 5 mL)
  2. 2
    Washwashed with EtOAc (5×20 mL, +sonication)
  3. 3
    Concentrationfinally concentrated in vacuo at r.t.

Procedure

The azide 67 (201 mg, 0.098 mmol) was dissolved in EtOAc (10 mL) and stirred with Pd—C (10%, (w/w), 100 mg) under H2 atmosphere for 3 h (TLC: toluene:EtOAc, 7:1). H2 was replaced by Ar then the mixture was filtered through celite (prewashed with MeOH and EtOAc, 5 mL), washed with EtOAc (5×20 mL, +sonication) and finally concentrated in vacuo at r.t. to obtain the amine 80 as a white solid (200 mg, 100%), used without further purification or characterization in the next step.
