Procedure

A mixture of 32.25 gm (124 mMol) N-(4-fluorobenzoyl)-4-nitroaniline and 3.2 gm platinum on carbon in 500 mL tetrahydrofuran was hydrogenated at room temperature for 18 hours with an initial pressure of 60 p.s.i. The reaction mixture was then filtered and the filtrate concentrated under reduced pressure to give 22.45 gm (79%) of N-(4-fluoro-benzoyl)-4-aminoaniline.

Workup

  1. filtrationThe reaction mixture was then filtered
  2. concentrationthe filtrate concentrated under reduced pressure
