Procedure

1.9 g. of 2-amino-1-nitro-4-phenylsulfonylbenzene is treated in methanol with hydrogen at 4 atmospheres in the presence of Raney nickel catalyst for 2 hours. The catalyst if filtered off and the filtrate stripped under vacuum. Recrystallization of the residue gives 1,2-diamino-4-phenylsulfonylbenzene.

Workup

  1. filtrationThe catalyst if filtered off
  2. customRecrystallization of the residue
