実験手順

To a solution of 3-fluoronitrobenzene (2 mL, 18.8 mmol) in DMSO (20 mL) was added Boc-piperazine (10 g, 56.4 mmol), after stirring at 100° C. for 3 days, the mixture was poured to ice water, the resulting precipitate was collected by filtration to give tert-butyl 4-(3-nitrophenyl)piperazine-1-carboxylate (1.91 g).
