Reaction Steps

Absolute ethanol (2 mL) was added to a two-necked round-bottomed flask containing palladium on carbon (0.09 g, 0.42 mmol). The reaction vessel was evacuated and purged with nitrogen three times. 1,2-Dimethyl-4-(2-fluoro-4-nitrophenyl)piperazine (1.06 g, 4.2 mmol) in absolute ethanol (10 mL) was added and the vessel purged thrice more with nitrogen. After purging thrice with hydrogen, the reaction was left to stir under a hydrogen atmosphere at room temperature for 18 h. The reaction mixture was filtered through a pad of Celite washing with additional ethanol. Excess ethanol was removed under reduced pressure to afford the title compound as an off-white oil. LC-MS (UV 215nm): 93%; m/z 224.35; 0.58 min.
