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).
