Yield: 10.43 g (89%)
Reaction Conditions:
in ethanol;water;hydrogen
Steps:
47 3-Chloro-1,2-phenylenediamine
Example 47 3-Chloro-1,2-phenylenediamine 2-Chloro-6-nitroaniline (14.10 g, 81.71 mmol), Raney-nickel (5.02 g of a 50% slurry in water), and ethanol (200 mL) were combined in an autoclave which was pressurized to 15 psig with hydrogen. The resulting mixture was allowed to stir overnight at RT. The mixture was then filtered through a pad of celite, which was subsequently washed with several portions of methanol, and the solvents were removed by rotary evaporation to afford 10.43 g (89%) of a viscous, brown oil, which darkened upon standing. MS (EI): m/z 143.1 (M+H).
