Reaction Steps

A solution of 1-fluoro-4-nitrobenzene (500 mg, 3.54 mmol) and tert-butyl piperazine-1-carboxylate (726 mg, 3.9 mmol) in dimethylformamide was treated with potassium carbonate (735 mg, 5.32 mmol) and the suspension was heated at 55° C. for 4 hours and then stirred overnight at room temperature. The reaction was poured into water and the suspension was filtered with water washes to provide the title compound after vacuum drying.
