Procedure

A solution of 4-(4-cyanophenyl)amino-2,6-dimethyl-3-nitropyridine (5.00 g, 18.6 mmol) in a mixture of dichloromethane (20 ml) and ethanol (100 ml) was hydrogenated at 20° C. over 10% palladium on charcoal (500 mg) at 138 kPa (20 p.s.i) for 3 hours. The catalyst was filtered off and the solvents were removed under reduced pressure to give the title compound as a brown solid (4.20 g, 94%).

Workup

  1. filtrationThe catalyst was filtered off
  2. customthe solvents were removed under reduced pressure
