Procedure

3 g of 2-benzylthio-3,5-dinitrobenzotrifluoride in 30 ml of tetrahydrofuran are hydrogenated in a glass hydrogenation apparatus for 22 hours at room temperature, using a total of 3 g of Raney nickel. For working up, the catalyst is removed by filtration and washed with tetrahydrofuran, the filtrate is evaporated, and the residue is directly processed as crude product (brownish liquid).

Workup

  1. customthe catalyst is removed by filtration
  2. washwashed with tetrahydrofuran
  3. customthe filtrate is evaporated
