Reaction Steps

To a solution of 1,3-difluoro-2-nitro-benzene (30 g, 0.188 moles) in EtOH (300 mL) was added 25% aq. ammonia solution (300 mL) and the resulting mixture was heated to 75° C. for 16 h then cooled and concentrated in vacuo. The residue was dissolved in EtOAc, washed with water and brine solution, dried (Na2SO4), filtered and concentrated to afford 25 g (85%) of 3-fluoro-2-nitro-phenylamine (138) as a brown solid which was used without any further purification.
