Procedure

To a solution of 56.6 gm (0.217 mole) 4-(4-fluorobenzoyl)aminonitrobenzene in 875 mL tetrahydrofuran were added 5.7 gm 5% platinum on carbon. The reaction mixture was hydrogenated at room temperature for 18 hours at initial hydrogen pressure of 60 p.s.i. The reaction mixture was then filtered and the filtrate concentrated under reduced pressure to give 49.3 gm (98.5%) of the desired compound.
