Versuchsvorschrift

2-(2-Nitroanilino)-5-methylthiophene-3-carbonitrile (100 g) is taken in ethyl acetate (1000 ml). The reaction mixture is then hydrogenated by 5% Pd/C (15 g) at 50-55° C. at 10-12 Kg pressure. The reaction mixture is filtered, and ethyl acetate is distilled off to get the title compound.

Aufarbeitung

  1. filtrationThe reaction mixture is filtered
  2. distillationethyl acetate is distilled off
