Versuchsvorschrift

A solution of 1.1 g (5.0 mmol) 4-methylamino-3-nitrobenzotrifluoride in 200 ml ethanol was hydrogenated at atm. pressure by using 5% Pd-C (0.15 g) as a catalyst. The reaction mixture was filtered and evaporated in vacuo to give 3-amino-4-methylaminobenzotrifluoride as crystals.

Aufarbeitung

  1. filtrationThe reaction mixture was filtered
  2. customevaporated in vacuo
