Procedure
Zinc dust (14 g) was added to a solution of 4-fluoro-3-nitro-N-phenyl-benzamide (1.99 g, 7.6 mmol) in acetic acid (80 mL) at 0° C. The mixture was stirred and allowed to warm to room temperature. After 4 hours, the mixture was filtered and the residue washed with ethyl acetate. The filtrate and washings were combined and taken to dryness by rotovap and the residue partitioned between ethyl acetate (200 mL) and saturated aqueous NaHCO3. The organic layer was washed with saturated brine, dried over MgSO4, filtered, and stripped of solvent. The residue was triturated in ethyl acetate/hexane and the suspended solid filtered off to afford the product (1.55 g); m.p. 167-170° C.
